Why did you not mention the DeepSpeech project by Mozilla?
DeepSpeech by Mozilla was abandoned many years ago and it is no longer under active development.

We recommend using other open-source models on this page that are still maintained.

r/LocalLLaMA on Reddit: Best local open source Text-To-Speech and Speech-To-Text?
August 24, 2024 -

I am working on a custom data-management software and for a while now I've been working and looking into possibility of integrating and modifying existing local conversational AI's into it (or at least developing the possibility of doing so in the future). The first thing I've been struggling with is that information is somewhat hard to come by - searches often lead me back here to r/LocalLLaMA/ and a year old threads in r/MachineLearning. Is anyone keeping track of what is out there what is worth the attention? I am posting this here in hope of finding some info while also sharing what I know for anyone who finds it useful or is interested.

I've noticed that most open source projects are based on Open AI's Whisper and it's re-implemented versions like:

  • Faster Whisper (MIT license)

  • Insanely fast Whisper (Apache-2.0 license)

  • Distil-Whisper (MIT license)

  • WhisperSpeech by github.com/collabora (MIT license, Added here 03/2025)

  • WhisperLive (MIT license, Added here 03/2025)

  • WhisperFusion, which is WhisperSpeech+WhisperLive in one package. (Added here 03/2025)

Coqui AI's TTS and STT -models (MPL-2.0 license) have gained some traction, but on their site they have stated that they're shutting down.

Tortoise TTS (Apache-2.0 license) and its re-implemented versions such as:

  • Tortoise-TTS-fast (AGPL-3.0, Apache-2.0 licenses) and its slightly faster(?) fork (AGPL-3.0 license).

StyleTTS and it's newer version:

  • StyleTTS2 (MIT license)

Alibaba Group's Tongyi SpeechTeam's SenseVoice (STT) [MIT license+possibly others] and CosyVoice (TTS) [Apache-2.0 license].

(11.2.2025): I will try to maintain this list so will begin adding new ones as well.

1/2025 Kokoro TTS (MIT License)
2/2025 Zonos by Zyphra (Apache-2.0 license)
3/2025 added: Metavoice (Apache-2.0 license)
3/2025 added: F5-TTS (MIT license)
3/2025 added: Orpheus-TTS by canopylabs.ai (Apache-2.0 license)
3/2025 added: MegaTTS3 (Apache-2.0 license)
4/2025 added: Index-tts (Apache-2.0 license). [Can be tried here.]
4/2025 added: Dia TTS (Apache-2.0 license) [Can be tried here.]
5/2025 added: Spark-TTS (Apache-2.0 license)[Can be tried here.]
5/2025 added: Parakeet TDT 0.6B V2 (CC-BY-4.0 license), STT English only [Can be tried here.], update: V3 is multilingual and has an onnx -version.

8/2025 added: Verbify-TTS (MIT License) by reddit user u/MattePalte. Described as simple locally run screen-reader-style app.

8/2025 added: Chatterbox-TTS (MIT License) [Can be tried here.]

8/2025 added: Microsoft's VibeVoice TTS (MIT Licence) for generating consistent long-form dialogues. Comes in 1.5B and 7B sizes. Both models can be tried here. 0.5B model is also on the way. This one also already has a ComfyUI wrapper by u/Fabix84/ (additional info here). Quantized versions by u/teachersecret can be found here

8/2025 added: BosonAI's Higgs Audio TTS (Apache-2.0 license). Can be tried here and further tested here. This one supports complex long-form dialogues. Extra prompting is supposed to allow setting the scene and adjusting expressions. Also has a quantized (4bit fork) version.

8/2025 added: StepFun AI's (Chinese AI-team source) Step-Audio 2 Mini Speech-To-Speech (Apache-2.0 license) a 8B "speech-to-speech" (Audio-To-Tokens + Tokens-To-Audio) -model. Added because related, even if bypasses the "to-text" -part.

---------------------------------------------------------

Edit1: Added Distil-Whisper because "insanely fast whisper" is not a model, but these were shipped together.
Edit2: StyleTTS2FineTune is not actually a different version of StyleTTS2, but rather a framework to finetuning it.
Edit3(11.2.2025): as suggested by u/caidong I added Kokoro TTS + also added Zonos to the list.
Edit4(20.3.2025): as suggested by u/Trysem , added WhisperSpeech, WhisperLive, WhisperFusion, Metavoice and F5-TTS.
Edit5(22.3.2025): Added Orpheus-TTS.
Edit6(28.3.2025): Added MegaTTS3.
Edit7(11.4.2025): as suggested by u/Trysem/, added Index-tts.
Edit8(24.4.2025): Added Dia TTS (Nari-labs).
Edit9(02.5.2025): Added Spark-TTS as suggested by u/Tandulim (here)
Edit9(02.5.2025): Added Parakeet TDT 0.6B V2. More info in this thread.

Edit10(29.8.2025): As originally suggested by u/Trysem and later by u/Nitroedge added Chatterbox-TTS to the list.

Edit10(29.8.2025): u/MattePalte asked me to add his own TTS called Verbify-TTS to the list.

Edit10(29.8.2025): Added Microsoft's recently released VibeVoice TTS, BosonAI's Higgs Audio TTS and StepFun's STS. +Extra info.

Edit11+12(1.9.2025): Added VibeVoice TTS's quantized versions and Parakeet V3.

I’ve been using alltalktts ( https://github.com/erew123/alltalk_tts ) which is based off of coqui and supports XTTS2, piper and some others. I’m on a Mac so my options are pretty limited, and this worked fairly well. If xtts is the model you want to go with, then maybe https://github.com/daswer123/xtts-api-server would work even better. Unfortunately most of my cases are in SillyTavern, for narration, and character tts, so these may not be the use case for you. The last link I shared might give you ideas for how to implement that on a real application though. Are you a dev-like person, or just enthusiastic about it? I ask because if you’re a dev with some Python knowledge, or willingness to follow code, the later link is actually pretty useful for ideas, in spite of being targeted towards SillyTavern. If not, this is whole space might be kind of hard to navigate at this point in time, and also will depend a lot on the hardware where you’ll be deploying this.
