LocalLLaMA was not impressed by another TTS clip so much as by a build log. The post that took off showed Qwen3-TTS running locally in real time, quantized through llama.cpp, with extra alignment work to make subtitles and lip sync behave.
Google’s new speech model moves control from hidden settings into the text itself: audio tags can steer style, pace, and delivery across 70+ languages. Gemini 3.1 Flash TTS is in preview through Gemini API, Google AI Studio, and Vertex AI, reaches Google Vids users, scores 1,211 Elo on Artificial Analysis, and watermarks outputs with SynthID.
Mistral AI said on March 26, 2026 that Voxtral TTS offers expressive speech, support for 9 languages and dialects, low latency, and easy adaptation to new voices. Mistral’s March 23 launch post says the 4B-parameter model can adapt from about three seconds of reference audio, reaches roughly 70ms model latency, supports up to two minutes of native audio generation, and is available by API and as open weights.
A March 2026 r/LocalLLaMA post with 123 points and 25 comments spotlighted `voxtral-voice-clone`, a project trying to train the missing codec encoder for Mistral’s Voxtral-4B-TTS-2603. The repo targets zero-shot cloning via `ref_audio`, which the original open-weight release could not support because the encoder weights were not included.
A high-signal LocalLLaMA thread formed around Voxtral TTS because Mistral paired low latency, multilingual support, and open weights in a part of the stack many teams still keep closed.
LiveKit said on X that xAI’s Grok text-to-speech is now available in LiveKit Inference with low-latency streaming, telephony readiness, and support for more than 20 languages. LiveKit’s docs say developers can access `xai/tts-1` through LiveKit Inference without a separate xAI API key or use the xAI plugin directly with `XAI_API_KEY`.
Kitten TTS v0.8 drew Hacker News attention by promising ONNX-based speech synthesis in 15M to 80M models that can run locally on CPUs, while commenters stress-tested real-world usability.
A March 9, 2026 LocalLLaMA discussion highlighted Fish Audio’s S2 release, which combines fine-grained inline speech control, multilingual coverage, and an SGLang-based streaming stack.
A well-received r/LocalLLaMA post described an Android app that turns EPUB books into spoken audio entirely on-device using Kokoro TTS. The project highlights how mobile inference speed, APK size, and thermal behavior now shape practical offline AI products.
Qwen3's TTS model encodes voices into 1024-dimensional vectors, enabling gender swapping, pitch adjustment, voice mixing, and semantic voice search through vector math — now available as a standalone lightweight encoder on HuggingFace.
A high-upvote LocalLLaMA thread highlighted KittenTTS v0.8, with community-shared details on 80M/40M/14M model variants, Apache-2.0 licensing, and an edge-friendly focus on local CPU inference.
A widely discussed LocalLLaMA post introduces open Kitten TTS v0.8 models (80M/40M/14M), emphasizing CPU-friendly deployment and sub-25MB footprint for the smallest variant.
