Why doesn’t the Gemini app do voice transcriptions?

I was trying to move from the ChatGPT app to the Gemini app, but unable to do so because the Gemini app doesn’t do voice transcriptions. ChatGPT allows me to upload audio files such as voice memos and have these transcribed. I sometimes use Apple built in voice transcription in my phone, but it doesn’t cover all languages and also I think Open AI’s model provides much better quality.

Does anyone know why Google has chosen not to provide this? It seems like such a core feature missing from the app.

How do you as a Gemini app user solve this issue? I don’t want to use AI Studio because I don’t want Google to train on my private voice memos.
