In their own words
Baidu Text-to-Speech
Baidu Text-to-Speech converts text into speech for applications and devices, with Chinese, English, mixed Chinese-English, and more than 70 voice styles available through its online service. Users can change speech rate, pitch, volume, and supported emotional effects; Chinese polyphonic characters can be annotated with pronunciation. Streaming synthesis can play audio nearly as text is entered, and long-text synthesis handles up to 100,000 Chinese characters in one request. Baidu provides HTTP and WebSocket APIs, online and offline SDKs, and Android and iOS SDKs for phones and smart devices. Offline synthesis is intended for settings with weak or no network access, including mobile apps, readers, robots, and smart hardware. Listed uses include audiobook reading, news and order announcements, and smart hardware. Short-text API requests must stay under 1,024 GBK bytes, with 120 bytes or less recommended. Export formats are MP3, PCM, and WAV. The service offers a free trial; offline trial and license plans are listed, while prices for other listed plans are not provided.
Chatterbox TTS
Chatterbox TTS is a family of open-source text-to-speech models from Resemble AI. Its listed choices include Turbo, Nano, Multilingual V3, and dedicated single-language models. Turbo supports tags that can prompt reactions such as sighs, gasps, coughs, and laughter; Nano is intended for on-device or CPU use when memory and latency budgets are tight. The README lists 23 languages for Multilingual. The project supports voice cloning, audio input, batch processing, voice isolation, and WAV export. Generated audio carries Resemble AI’s PerTh watermark. The repository is MIT licensed, and its listed plan costs nothing for research and development. Resemble says it has stopped offering voice generation as a commercial product, while its models remain open and free for research and development. The README provides pip and source installation instructions and describes Python 3.11 on Debian 11, with CUDA, CPU, and MPS device options. Listed platforms are Linux, macOS, and self-hosted.
