Moshi AI

Moshi AI

What is Moshi AI?

Moshi AI is a speech-native conversational model from Kyutai, a Paris-based open-science research lab. Instead of chaining speech recognition, text generation, and text-to-speech, Moshi processes audio directly and holds full-duplex voice conversations with minimal latency.

Its multi-stream design runs separate channels for the user, Moshi's spoken output, and an Inner Monologue text stream that improves coherence. That setup lets Moshi listen and talk at the same time, handle overlaps, interruptions, and backchanneling like a real conversation rather than rigid speaker turns.

Moshi is built on Helium, a 7B language model, and Mimi, Kyutai's neural audio codec. Weights and inference code ship for PyTorch, Rust, and MLX, and you can try it in the browser at moshi-chat.kyutai.org. Researchers, voice AI developers, and anyone building real-time spoken interfaces will find the most value here.

What is tts4free?

tts4free.com is a free online text-to-speech converter that turns typed text into downloadable audio using Microsoft Edge's online voices. Paste up to 5,000 characters, pick a voice, and hit Convert without creating an account or paying anything.

The site runs on Next.js with edge-tts and pulls from Microsoft's natural-sounding online TTS catalog. A separate VoiceSample page lists voices by language and style so you can preview options before converting your own text.

It fits students, language learners, accessibility users, and anyone who wants written content read aloud in the browser. The interface stays minimal: text box, voice selector, and a single convert action.
