voice memo transcript language selection

I recently updated to iOS 18 and was excited to see that the transcript was available after finishing a voice memo. However, I was dismayed to find that the voice memo, recorded in Chinese, produced a garbled English transcript. Where is the button to select the transcription language? This seems like a major oversight for a large, multinational user base like Apple's.

It would be really disheartening if they automatically set the transcription language to match the user's iPhone or Mac language without any way to select.
