Ai Audio Translator

Transmonkey’s Audio Translator extension turns any audio or video into multilingual content directly in your browser. It combines OpenAI Whisper for transcription, large language models such as ChatGPT, Gemini and Claude for translation, and OpenAI TTS for dubbing, so you can move from original audio to natural‑sounding voiceovers in over 130 languages without leaving.

With a few clicks, you can upload a local file or paste an online URL, let the extension transcribe and translate, then download both the translated audio and the accompanying transcript or subtitle files. Background music and ambience are preserved while the translated voice track is mixed in, which makes the output suitable for tutorials, marketing videos, webinars and more.

Key capabilities include support for common audio and video formats such as MP3, MP4, MOV, M4V and WAV, file sizes up to 500 MB and 60 minutes, and coverage of 130+ languages including English, Chinese, Spanish, Arabic, French and Russian. The same AI translation stack that powers Transmonkey’s document, image and video tools is used here, so teams can keep a consistent translation quality across all media types.

Using the extension is straightforward: choose or open the media you want to translate, set source and target languages, click “Translate”, and wait for processing to finish. When the job is done, the extension provides downloadable translated audio plus text and subtitle outputs that you can edit, repurpose or share with your team.

The service offers free trial credits for new accounts, with paid plans available when you need higher volume or frequent usage. Files are processed on secure US‑based servers and translation data is deleted within a short time window, while only a lightweight history is stored locally in the browser to help you track past tasks.
