Most indie games ship without voice acting. Not because developers do not want it, but because hiring voice actors is expensive, scheduling them is slow, and revising recorded lines after the script changes means paying them again. So the game gets subtitles and silence, and it is a little bit flatter for it.
ElevenLabs has made this calculation genuinely worth revisiting. The voice quality is not "pretty good for AI." On certain voice types and delivery styles it is difficult to distinguish from a recorded human performance without a direct A/B comparison. It is not perfect across the board, but it is good enough that the question "should I voice my game?" now has a different answer for solo developers than it did two years ago.
This guide covers what ElevenLabs can and cannot do for game development specifically, how the credit and pricing system actually works, how to set up a voice cloning workflow for consistent character voices, and how to get the audio into Unity.
What ElevenLabs Does
ElevenLabs converts text to speech using AI models trained on large amounts of human voice recordings. You type a line of dialogue, pick a voice, and get an audio file back. The voices have natural variation in pacing, emphasis, and emotional tone — not the flat robotic cadence of older TTS systems.
There are three main ways to get voices:
- Pre-made voices — a library of built-in voice options across different accents, ages, and tones. No setup required.
- Voice Design — generate a synthetic voice with specific characteristics (age, accent, tone, gender) without providing any recording. Good for creating unique character voices that do not sound like a specific real person.
- Voice Cloning — upload recordings of a real voice (your own, a voice actor's with permission, or a custom character recording) and generate new lines in that voice.
For game development, Voice Design and Voice Cloning are where the practical value lives. The pre-made voices are fine for narrators and generic NPCs, but any character who appears repeatedly needs a consistent, distinctive voice — which means either picking one pre-made voice and sticking to it, or cloning a voice specifically for that character.
Pricing and the Credit System
ElevenLabs bills based on credits. Credits are consumed by every generation, with different models and quality settings costing different amounts per character of text. The relationship between credits and usable audio time is not straightforward, and the pricing page is not the most transparent thing to read.
Here is what the relevant tiers actually get a solo game developer, as of mid-2026:
| Plan | Monthly Price | Credits | Approx. Audio | Commercial Rights | Voice Cloning |
| Free | $0 | 10,000/month | ~10 min (Multilingual) or ~20 min (Flash) | No — attribution required | No |
| Starter | $5/month | 30,000/month | ~30 min (Multilingual) or ~60 min (Flash) | Yes | Instant cloning only |
| Creator | $22/month | 100,000/month | ~100 min (Multilingual) | Yes | Professional cloning |
| Pro | $99/month | 500,000/month | ~500 min | Yes | Professional cloning |
Two things about this table worth flagging before you make any decisions.
First: the free plan has no commercial usage rights. Content created on the free plan requires ElevenLabs attribution and cannot be used in a monetized product, client work, or anything revenue-adjacent. For a game you plan to sell or distribute through any store, you need at minimum Starter at $5/month. This trips up a lot of people who test the free tier, like the results, and then discover the fine print when they try to ship.
Second: instant voice cloning versus professional voice cloning is a meaningful quality difference. Instant cloning works from a minute or two of audio and is available on Starter. Professional cloning requires more training data and is available from Creator upward — it produces more stable, natural results across long dialogue sessions. For a main character who speaks hundreds of lines, professional cloning is worth the upgrade. For a minor NPC with a dozen lines, instant cloning is probably fine.
Annual billing saves roughly 17% across all tiers. Always verify current pricing at elevenlabs.io before subscribing — plans and credit allocations change frequently and the pricing page is the authoritative source.
Part 1: Setting Up a Character Voice
The fastest way to get started is using one of the pre-made voices from the Voice Library. Go to the Voices section, browse by category (narrator, villain, young adult, and so on), preview them, and save the ones that feel right for your character types. Each saved voice appears in your generation panel.
For characters who need a distinctive, custom voice, Voice Design is the better option.
Voice Design Workflow
- Go to Voices > Voice Design in the ElevenLabs interface.
- Describe the voice in the text prompt: "A gruff middle-aged man, slightly raspy, slight Eastern European accent, sounds like he has seen too much war." ElevenLabs generates multiple voice variants matching that description.
- Preview each variant with a sample line. Generate more variants until one fits.
- Save the voice to your voice library. It now appears in every generation panel as a selectable option.
Voice Design voices are synthetic — they are not trained on or derived from any specific real person's recordings. They are consistent across generations, unlike a cloned voice that can sometimes drift slightly on unusual phoneme combinations.
Instant Voice Cloning (Starter and Above)
If you want to record your own voice and use it as a character voice, or if you have hired a voice actor for a short session and want to generate additional lines without rebooking:
- Go to Voices > Add a New Voice > Instant Voice Clone.
- Upload 1-3 minutes of clean audio with minimal background noise. A phone recording works; a recording with music underneath does not.
- Name the voice and save it.
- Generate new lines in that voice.
For instant cloning, one to three minutes of clean mono audio at 22 kHz or higher produces a usable clone. The voice holds up for short lines but can sound slightly off on very long sentences or unusual phrases. Test across a range of your actual dialogue before committing to it for a main character.
Part 2: Generating Dialogue
Go to Text to Speech in the navigation. Select your character voice, paste a dialogue line, and generate. The output is a .mp3 or .wav file you can download immediately.
Settings That Change the Output
| Setting | What It Does | Game Dev Starting Point |
| Model | Eleven Multilingual v2 for best quality; Flash v2.5 for faster/cheaper generation at slightly lower quality. | Use Multilingual for final lines, Flash for draft review. |
| Stability | Higher stability = more consistent but flatter delivery. Lower = more expressive but can drift between generations. | 0.4-0.6 for most NPC dialogue. Lower for emotional scenes. |
| Similarity Boost | For cloned voices, how closely the output matches the original recording. Higher values can cause artifacts. | 0.7-0.8. Above 0.9 often sounds unnatural. |
| Style Exaggeration | Emphasizes the speaking style in the voice. Can add character but also amplify oddities. | 0-0.3 for normal dialogue. Higher for stylized characters. |
The Speaker Boost checkbox is worth enabling for any voice that sounds slightly muddy on playback — it adds a processing pass that clarifies the audio. It costs slightly more credits per generation.
Directing Delivery Through Text
ElevenLabs does not have a separate emotion selector for most models. You direct the emotional delivery through the text itself — punctuation, pacing cues, and in some cases explicit stage direction in brackets.
These techniques actually work:
- Ellipsis for hesitation: "I... I don't know what to say."
- Capitalization for stress: "I told you NOT to open that door."
- Dashes for interrupted speech: "Wait, before you go — listen to me."
- Brackets for tone direction (Eleven v3): "[whispering] They're still out there."
The bracket-based direction is a v3 feature and not available on all models. Test which techniques work on your specific voice and model combination rather than assuming all of them apply.
Part 3: Getting Audio Into Unity
Unity supports .mp3 and .wav imports directly. The workflow is simple but there are a few things that will save you time at scale.
Basic Import
- Download generated audio as .wav (higher quality, larger file) or .mp3 (smaller, fine for most dialogue).
- Drag into a designated folder in your Unity Project window — something like Assets/Audio/Dialogue/CharacterName/.
- Select the imported clip and check the Inspector settings: set Compression Format to Vorbis for dialogue (better compression than PCM), set Load Type to Streaming for long files or Decompress on Load for short lines.
- Assign to an AudioSource component in your NPC's script, or reference it in your dialogue system's audio playback logic.
Managing a Large Dialogue Library
A game with dozens of NPCs and hundreds of dialogue lines generates a lot of audio files. A naming convention from the start prevents the folder from becoming unmanageable:
NPC_Guard_Line001_Idle.wav NPC_Guard_Line002_Alert.wav NPC_Merchant_Line001_Greeting.wav
If your dialogue system uses a ScriptableObject-based structure (covered in the ScriptableObjects guide from this series), you can store AudioClip references directly in the dialogue data assets alongside the text. This keeps dialogue text and audio tied together in the same place rather than scattered across separate folders that drift out of sync as the script changes.
What Works Well and What Does Not
ElevenLabs is genuinely impressive for certain voice types and delivery styles. Calm narration, conversational NPC chatter, villain monologues with measured delivery, elderly characters with gravelly voices — these tend to come out well without much tweaking.
It struggles with:
- Shouting and extreme emotion. Screaming, rage, and intense fear often come out sounding strained or artificial. These are the lines worth recording with a real voice actor if any lines in your game are.
- Non-English phonemes in otherwise English text. A character name like "Xrathul" or a place name like "Aelionthar" will be mispronounced in ways that vary between generations. Test proper noun pronunciation early.
- Very long lines without natural pause points. Lines over 200-300 characters sometimes have pacing issues. Break long dialogue into multiple shorter generations and edit them together in an audio editor if needed.
- Singing. ElevenLabs has a music feature but it is not designed for character singing in the way game vocals usually work. For anything sung, a real recording remains the practical option.
The Sound Effects Generator is worth knowing about but is not a replacement for a proper game audio library. It generates short sound effects from text prompts — "heavy wooden door creaking open," "distant thunderstorm," "coins dropping on stone floor." The results are inconsistent. Sometimes usable, sometimes clearly artificial. Worth testing on any specific sound you need and cannot source elsewhere, but not something to build a full audio pipeline around.
ElevenLabs vs Alternatives
| Tool | Strengths | Weaknesses | Price |
| ElevenLabs | Best overall voice quality in 2026, voice cloning, large voice library, good emotional range on supported delivery styles. | No commercial rights on free tier, credit system is confusing, struggles with extreme vocal delivery. | Free; $5/month (Starter); $22/month (Creator) |
| Murf AI | Clean interface, good for narration and corporate-style voices, integrated editing tools. | Lower emotional range than ElevenLabs, less convincing for character acting versus narration. | Free tier; paid from $19/month |
| Play.ht | Wide voice selection, API-friendly for automation, good multilingual support. | Quality ceiling slightly below ElevenLabs on character voices. | Free tier; paid from $31/month |
| Real voice actors | Authentic delivery, natural extreme emotion, human direction, fully licensable. | Cost, scheduling, revision cycles, not scalable for large NPC casts on indie budgets. | $100-500+ per hour session |
The honest comparison to real voice actors is worth thinking through rather than dismissing. For a protagonist with 500+ lines across 20 hours of gameplay, ElevenLabs is not going to produce the same emotional performance a professional actor would. For 50 lines of ambient dialogue across 30 different minor NPCs, it absolutely is the practical choice.
Common Problems
The voice sounds right sometimes but inconsistent across multiple generations of the same line.
Stability is too low. Raise the Stability slider toward 0.6-0.7. If consistency still varies, the voice itself may be inherently unstable on this model — try a different model (Multilingual v2 tends to be more consistent than Flash for character work) or regenerate and use the most consistent take.
Proper nouns and character names are being mispronounced.
Spell them phonetically in the text input. "Xrathul" becomes "Zrathool" or "Zr-ath-ul" depending on which phonetic spelling produces the correct sound on your specific voice. Test phonetic spelling early in production — going back through hundreds of lines to fix a name pronunciation is slow.
The audio has a slight robotic or unnatural quality at certain points.
Speaker Boost is the first thing to try — it adds clarity and reduces the uncanny valley quality on some voices. Also check whether the model is set to Flash (faster, lower quality) rather than Multilingual v2. For voice clones specifically, lowering Similarity Boost from above 0.85 to around 0.75 often improves naturalness.
Free tier audio cannot be used in the game.
This is not a technical problem, it is a terms of service issue. The free tier has no commercial usage rights. Upgrade to at least Starter ($5/month) before generating any audio you intend to include in a distributed or monetized game.
A Practical Dialogue Pipeline for Solo Developers
This is the workflow that makes ElevenLabs actually manageable when you have more than a handful of lines to generate.
- Finalize the script first. Generate audio for lines that are locked. Generating audio for dialogue that later changes costs credits twice and creates file management headaches.
- Create one voice per major character. Either a pre-made voice you have tested across a range of line types, a Voice Design voice you have generated and saved, or a cloned voice. Stick to it throughout production.
- Generate in batches by character. Generate all lines for one character in one session while the settings and voice are loaded. Switching between characters mid-session wastes time on setup and makes it harder to catch inconsistencies.
- Name files consistently from the start using the convention described above. No renaming later.
- Keep a generation log. A simple spreadsheet with line ID, text, voice used, generation date, and Unity file path. When the script changes and you need to regenerate specific lines, you can find exactly which file needs replacing without listening through everything.
What to Do With It Now
Create a free account at elevenlabs.io — no credit card required. Generate ten lines using the pre-made voice library to get a feel for quality before worrying about custom voices or cloning. Try the same line with different Stability settings to see how much that single slider changes the output. Then try Voice Design with a specific character concept from your current project.
If the quality is good enough for your game's dialogue needs, upgrade to Starter before generating anything you plan to actually ship. Five dollars a month for commercial rights and thirty minutes of high-quality dialogue audio per month is genuinely good value for an indie developer.
