| Description | Vapi is an API-first platform for building, testing, and deploying voice AI agents that handle phone calls and conversations across telephony, web, and mobile. It combines speech-to-text, language models, and text-to-speech, lets developers bring their own models, and provides orchestration, real-time monitoring, automated testing, and enterprise-grade reliability. It supports over 100 languages and can scale to millions of calls with sub-500ms latency. | SpeechLab is an AI localization and dubbing platform that transcribes, translates, captions, subtitles, and dubs video and audio in 50+ languages, all in a single editor. It's built for media publishers, creators, enterprise marketing teams, corporate L&D departments, and localization service providers who need to review and refine every word, voice, and segment before shipping. What sets it apart from black-box dubbing tools is fine-grained control — SRT import, waveform and segment-level editing, speaker diarization, source-voice cloning, and re-dubbing a single segment instead of the whole project. |
