Voice message transcript resets during transcription

## Steps to reproduce
1. Long press on a voice message
2. Choose transcribe
3. Choose a language

### Expected behaviour
The transcript is generated in the new view.

### Actual behaviour
The transcript is generated in the new view, but resets every sentence or so, in a way that only allows the user to quickly read the contents before they disappear.
(I'm transcribing Italian messages if that's relevant)
