Rythmex

Rythmex is an online audio and video transcription tool. You upload a recording, and Rythmex converts the speech into text quickly, in more than 140 languages and from more than 20 file formats, including MP3, WAV, OGG, AMR and video files.

It is used to transcribe interviews, lectures, podcasts, meetings, voice notes and call-centre recordings. The transcript can be edited and exported in different text formats, and features such as subtitles and translation help repurpose content. Rythmex is designed to be simple: upload, transcribe and use, with no installation needed.

Good fit if you: need fast, accurate transcriptions of recordings in many languages without installing software.
Less ideal if you: need a developer API for real-time transcription inside your own app.

Pricing: free minutes to try; paid plans and pay-as-you-go options for more transcription.
