AI Voice Tools for Game Characters in 2026
AI voice for games has had a rough couple of years. Several of the companies developers relied on have shut down or walked away from voice entirely.
Here is where things stand as of October 2026, and what to use now.
What happened to the voice tools you remember
| Tool | What happened |
|---|---|
| Replica Studios | Shut down June 30, 2025; unexported audio was lost |
| Coqui | Company closed in early 2024; XTTS weights remain non-commercial |
| Resemble AI | Pivoted to deepfake detection in August 2026; no new voice customers |
| Hume AI | Sunsetting its TTS and EVI APIs on November 13, 2026 |
| Inworld | Still sells strong TTS, but retired its character tools |
Two kinds of voice tool
Voice-over generators turn a script into audio files. They are right for cutscenes, barks and narration: anything written in advance.
Speaking characters listen to the player and answer out loud in real time. They need speech-to-text, a character that decides what to say, and streamed text-to-speech, all with low latency.
Options in 2026
| Tool | Voice-over | Speaking characters | Cloning | Engine SDK |
|---|---|---|---|---|
| Neocortex | Via TTS API | Yes, full characters | Yes, plus voice design | Unity, Unreal, Godot (beta) |
| ElevenLabs | Yes, excellent | Voice agents, not game characters | Yes | No Unity SDK |
| Inworld TTS | Yes | Build it yourself on Runtime | Yes | Runtime SDKs |
| OpenAI and Gemini voices | Yes | Build it yourself | No | No official Unity SDK |
| Open models (Chatterbox, Coqui forks) | Yes, self-hosted | Build it yourself | Yes | No, and check each licence |
Lessons from the shutdowns
- Export everything. Keep your generated audio and voice samples in your own storage.
- Check the licence. Some open models allow only non-commercial use.
- Prefer platforms with an exit. Self-hosting or local options reduce the risk of losing your pipeline.
Why game teams choose Neocortex for character voices
Voice cloning and voice design. Clone from a 10-second sample you have the rights to, or describe a voice and choose from generated options.
Characters, not just audio. Each voice belongs to a character with a personality, knowledge and actions, and players can speak to it.
Streamed in your engine. Replies start fast, including in Unity WebGL builds.
Commercial use on the Pro plan and above, and self-hosting for studios that need it.
