In their own words
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.
Fish Audio
Fish Audio provides text-to-speech, voice cloning, speech-to-text, voice agents, and other audio tools. Its text-to-speech controls cover emotion and expression, real-time generation, multilingual output, speed, volume, and model parameters. Fish Audio says TTS supports eight languages with native accents and its platform hosts more than 2,000,000 voices. Developers can use the API for speech generation, voice cloning, and transcription through REST, WebSocket streaming, and official Python and TypeScript SDKs. The listed platforms include web, Linux, macOS, Windows, API access, and self-hosting. Use cases named by the company include video voiceovers, audiobook narration, character voices, and conversational chatbots. The Free Tier costs nothing and allows 8,000 monthly credits, up to 7 minutes of generation, and personal, non-commercial use. Plus costs $11 a month, billed $132 billed annually; paid plans are listed from $15/mo. Commercial use is listed as available. Enterprise deployments include VPC, on-premises, air-gapped, and sovereign cloud options.
