EmotiVoice is an open-source text-to-speech engine that speaks English and Chinese with over 2000 voices. Its main feature is emotional synthesis across emotions such as happy, excited, sad and angry. It provides a web interface and a scripting interface for batch generation.
Applio is an open-source AI voice conversion suite. It provides voice conversion, real-time voice changing, speech synthesis, model training, voice blending and audio analysis. The project states it is MIT licensed and runs on Windows, macOS and Linux, with a desktop app or Gradio WebUI, and no accounts or telemetry.
Works with speech, voice, music or other audio using machine-learning models.
A transcription API built on OpenAI Whisper that converts audio and video files to text. It supports file uploads and remote URLs, multiple output formats, and model size selection for speed versus accuracy. A no-code dashboard offers drag-and-drop transcription. Pricing is pay-as-you-go with credit bundles, and files auto-delete after 24 hours.
AudioArena is a site for benchmarking and comparing voice models through real conversations. It offers AudioAgentBench, a set of six static multi-turn voice agent benchmarks, scored across five dimensions, and lets users select a benchmark, model, and run to view turn-by-turn transcripts.
AudioLDM is a text-to-audio system built on a latent space that learns continuous audio representations from CLAP latents. It generates text-conditional sound effects, human speech and music, and enables zero-shot text-guided audio style transfer, inpainting and super-resolution.
CMUSphinx is an open source speech recognition system for mobile and server applications. It supports C, C++, C#, Python, Ruby, Java and JavaScript, and Unix, Windows, iOS, Android and hardware platforms. The related PocketSphinx 5.1.0 release adds Python 3.14 support and pre-built wheels for Linux/arm64.
