Show HN: Speech and Audio To Text – Transcribe voice messages offline

6 points by 8mobile 9 days ago

Hi HN, I’d like to share a side project I recently finished: Speech & Audio To Text, a small iOS utility to transcribe voice messages from apps like WhatsApp, Telegram, and Voice Memos — fully offline and without sending any data to the cloud.

The motivation was personal. I often receive voice notes when I can't listen to them — during meetings, while commuting on noisy trains, or when I don’t want to disturb others. I used to rely on an app that handled this well, until it moved to a subscription model and started requiring constant internet access.

I wanted something that would:

- Work offline - Not send audio to any server - Be available with a single, one-time purchase - Support WhatsApp and Telegram voice messages directly - Handle multiple languages

So I built it. It’s completely local, lightweight, and doesn't use any AI or external APIs. The speech recognition relies on on-device iOS capabilities, and supports over 60 languages depending on system settings.

I'd love to hear your feedback or suggestions. Thanks for checking it out.
