Fish Audio is an AI text-to-speech and voice cloning service that provides studio-grade TTS with emotion control and a large library of voices across multiple languages. The service is presented at fish.audio and markets features such as voice cloning and an industry-leading voice generator.

Speechify is an AI voice and text-to-speech platform that reads written material aloud and also provides speech-to-text, conversational, and business-focused AI tools. Its SpeechifyAI service offers text-to-speech and realtime voice-agent APIs through a single interface, with streaming synthesis, zero-shot voice cloning from a consented reference clip, SSML-based emotion control, and multilingual output for English, German, Mexican Spanish, French, Italian, and Brazilian Portuguese. The service includes the Simba model family, which the site describes as streaming-native speech models designed to model voice identity, expression, and language for realtime conversation. Speechify was co-founded by Cliff Weitzman, who initially built it to consume written material through audio.

VoiceStudio is an open-source, fully local desktop application for voice cloning and design, text-to-speech, transcription, dictation, video dubbing, and long-form audio production. It runs on macOS Apple Silicon, Windows, Linux, or Docker and keeps voices, projects, settings, and generated files on the machine by default. The application combines a Tauri desktop shell, a React and Vite interface, and a local FastAPI backend with registries for multiple TTS and ASR engines. Its workflows can transcribe and translate video, preserve speaker assignments, synthesize replacement speech, render audiobook chapters, separate vocals, diarize speakers, process batch jobs, and route work to CPU, CUDA, Apple Silicon MPS/MLX, ROCm, or optional remote workers. It also exposes local REST, SSE, WebSocket, OpenAI-compatible audio, and MCP interfaces, including speech synthesis and transcription endpoints. VoiceStudio is licensed under AGPL-3.0; downloaded models and tokenizers retain their own licenses. The local workflow requires no account, API key, subscription, or usage meter, although remote workers, configured external ASR endpoints, analytics, and other network-backed functions are opt-in. The repository describes the software as an active beta and distributes packaged desktop releases as well as source code.
