About Telegram voice messages
Telegram voice messages are saved as OGG (Opus). Download them from Telegram Desktop or share them from your phone and upload them as they are: no conversion and no Telegram Premium needed.
How to save a Telegram voice message
- 1On a computer (Telegram Desktop): right-click the voice message and choose Save As. An
.oggfile will be downloaded. - 2On your phone: forward the voice message to your Saved Messages and download it later from Telegram Desktop, or use the system share option if your version offers it.
- 3Upload the file as it is to the tool above:
.oggand.opusfiles are transcribed directly. - 4Choose the language, press Transcribe and review the text with the synced audio.
Doesn't Telegram transcribe already?
Telegram Premium includes voice-to-text for voice messages inside the chat. If you don't have Premium, the message is long, it's in a language that isn't recognized well, or you need the text in Word, with timestamps or for your records, uploading it here is the alternative: you only pay for the audio's minutes, with no subscription.
Tips
- Telegram's round video messages can be transcribed too: save them and upload the MP4.
- If you have many voice messages from one chat, Telegram Desktop can export the chat history including voice messages, and you upload the ones you need.
- Telegram voice messages use the Opus codec, just like WhatsApp: they're tiny and upload in seconds. More in OGG and OPUS.
