Working with transcript editor

Transcription converts spoken audio into text. Translation changes the language of that text. Text-to-speech creates audio from written words. They can form one workflow, but each stage needs its own review: a transcription error can carry through into a translated subtitle or voiceover.

Common questions

Are speaker labels part of ordinary transcription?

Not necessarily. Transcription identifies words; diarization estimates which speaker spoke when. A label such as Speaker 1 does not establish a person’s identity. Overlapping voices can make both tasks harder.

Is reading text aloud the same as downloading generated speech?

No. Browser read-aloud uses voices available to the browser or operating system, and some voices use remote services. Creating a downloadable audio file needs a separate synthesis and export pipeline.
