Its focus is narrow but practical: speech that sounds like a person talking, rather than a narrator reading a script. That makes it a natural fit for voice output in large language model assistants and other dialogue systems, where cadence, pauses and prosody matter more than broadcast-style clarity. The model supports Chinese and English, and was trained on a very large corpus of audio in both languages, which is why outputs tend to sound fluent in mixed-language and conversational contexts. Because it is released openly, developers can install it locally with pip, load the pretrained weights and generate audio from plain text with only a few lines of code. The site at chattts.com is a community-run resource rather than the official vendor page: it gathers project background, a step-by-step usage guide, a downloadable code walkthrough and a lightweight online demo. It also points visitors toward related voice-cloning tools. Since the model is open source, there is no subscription — the practical costs are your own compute and setup time. **Pricing & Plans:** Free and open source. The model code and pretrained weights can be downloaded from GitHub and run locally at no cost; the site's hosted demo is also free to try. Your real cost is your own hardware or cloud GPU time. - **Conversational focus:** Tuned for dialogue rather than narration, so output carries natural rhythm, pauses and intonation that suits assistant-style speech. - **Chinese and English:** Handles both languages, making it practical for multilingual assistant experiences and content that switches between them. - **Open-source model:** Code and pretrained weights are publicly available, so you can run it locally, inspect it and fine-tune it on your own audio. - **Simple Python workflow:** Install with pip, load the model, pass a list of text strings and receive waveform arrays ready to play or save. - **Community documentation and demo:** A guided setup path, FAQ and an in-browser example make it easy to hear results before committing to a local installation. **Strengths:** Free and openly licensed, with no subscription or per-character fees; Speech quality is notably natural for conversational, assistant-style dialogue; Runs locally, giving you full control over data and inference; Backed by a large community and an actively starred GitHub repository **Limitations:** No managed cloud service from the project itself, so you must handle hosting and GPUs; Real-time generation demands meaningful compute resources; Quality can vary with very long or complex input text [Profile (Markdown)](https://openaitools.app/tool/chattts.md) ## Speechify Speechify is a voice AI assistant built around listening, reading and writing with your voice.
