Recent Changes

Raccoon Mission Updates, 2025-11-09

• 🦝 Production-ready multiprocess architecture - 4 uvicorn workers for true concurrency, bypassing Python's GIL
• 🦝 Voice auto-detection - model parameter now optional, automatically selects correct engine from voice name
• 🦝 Voice cache initialization fix - All worker processes now properly initialize voice-to-model lookup cache
• 🦝 Args initialization fix - Worker processes now have access to server configuration via DefaultArgs class
• 🦝 235/245 voices working (95.9% hydration success rate):
  • Piper: 55/55 voices (100%)
  • XTTS: 6/8 voices (75%)
  • Silero: 142/148 voices (95.9%)
  • Kokoro: 32/34 voices (94.1%)
• 🦝 Extended /v1/voices endpoint - Returns all available voices with engine metadata
• 🦝 Makefile targets - make hydrate (test all voices), make load-test (concurrent stress test)
• 🦝 Comprehensive docs - See docs/CLAUDE.md, docs/MODELS.md, docs/MIRRORS.md, docs/AUDIT.md

Version 0.18.2, 2024-08-16

• Fix docker building for amd64, refactor github actions again, free up more disk space

Version 0.18.1, 2024-08-15

• refactor github actions

Version 0.18.0, 2024-08-15

• Allow folders of wav samples in xtts. Samples will be combined, allowing for mixed voices and collections of small samples. Still limited to 30 seconds total. Thanks @nathanhere.
• Fix missing yaml requirement in -min image
• fix fr_FR-tom-medium and other 44khz piper voices (detect non-default sample rates)
• minor updates

Version 0.17.2, 2024-07-01

• fix -min image (re: langdetect)

Version 0.17.1, 2024-07-01

• fix ROCm (add langdetect to requirements-rocm.txt)
• Fix zh-cn for xtts

Version 0.17.0, 2024-07-01

• Automatic language detection, thanks @RodolfoCastanheira

Version 0.16.0, 2024-06-29

• Multi-client safe version. Audio generation is synchronized in a single process. The estimated 'realtime' factor of XTTS on a GPU is roughly 1/3, this means that multiple streams simultaneously, or speed over 2, may experience audio underrun (delays or pauses in playback). This makes multiple clients possible and safe, but in practice 2 or 3 simultaneous streams is the maximum without audio underrun.

Version 0.15.1, 2024-06-27

• Remove deepspeed from requirements.txt, it's too complex for typical users. A more detailed deepspeed install document will be required.

Version 0.15.0, 2024-06-26

• Switch to coqui-tts (updated fork), updated simpler dependencies, torch 2.3, etc.
• Resolve cuda threading issues

Version 0.14.1, 2024-06-26

• Make deepspeed possible (--use-deepspeed), but not enabled in pre-built docker images (too large). Requires the cuda-toolkit installed, see the Dockerfile comment for details

Version 0.14.0, 2024-06-26

• Added response_format: wav and pcm support
• Output streaming (while generating) for tts-1 and tts-1-hd
• Enhanced generation parameters for xtts models (temperature, top_p, etc.)
• Idle unload timer (optional) - doesn't work perfectly yet
• Improved error handling

Version 0.13.0, 2024-06-25

• Added Custom fine-tuned XTTS model support
• Initial prebuilt arm64 image support (Apple M-series, Raspberry Pi - MPS is not supported in XTTS/torch), thanks @JakeStevenson, @hchasens
• Initial attempt at AMD GPU (ROCm 5.7) support
• Parler-tts support removed
• Move the *.default.yaml to the root folder
• Run the docker as a service by default (restart: unless-stopped)
• Added audio_reader.py for streaming text input and reading long texts

Version 0.12.3, 2024-06-17

• Additional logging details for BadRequests (400)

Version 0.12.2, 2024-06-16

• Fix :min image requirements (numpy<2?)

Version 0.12.0, 2024-06-16

• Improved error handling and logging
• Restore the original alloy tts-1-hd voice by default, use alloy-alt for the old voice.

Version 0.11.0, 2024-05-29

• 🌐 Multilingual support (16 languages) with XTTS
• Remove high Unicode filtering from the default config/pre_process_map.yaml
• Update Docker build & app startup. thanks @justinh-rahb
• Fix: "Plan failed with a cudnnException"
• Remove piper cuda support

Version: 0.10.1, 2024-05-05

• Remove runtime: nvidia from docker-compose.yml, this assumes nvidia/cuda compatible runtime is available by default. thanks @jmtatsch

Version: 0.10.0, 2024-04-27

• Pre-built & tested docker images, smaller docker images (8GB or 860MB)
• Better upgrades: reorganize config files under config/, voice models under voices/
• Compatibility! If you customized your voice_to_speaker.yaml or pre_process_map.yaml you need to move them to the config/ folder.
• default listen host to 0.0.0.0

Version: 0.9.0, 2024-04-23

• Fix bug with yaml and loading UTF-8
• New sample text-to-speech application say.py
• Smaller docker base image
• Add beta parler-tts support (you can describe very basic features of the speaker voice), See: (https://www.text-description-to-speech.com/) for some examples of how to describe voices. Voices can be defined in the voice_to_speaker.default.yaml. Two example parler-tts voices are included in the voice_to_speaker.default.yaml file. parler-tts is experimental software and is kind of slow. The exact voice will be slightly different each generation but should be similar to the basic description.

...

Version: 0.7.3, 2024-03-20

• Allow different xtts versions per voice in voice_to_speaker.yaml, ex. xtts_v2.0.2
• Quality: Fix xtts sample rate (24000 vs. 22050 for piper) and pops
