The only requirement is having the audio file. On WhatsApp and Telegram, you must save the voice message on your device or in the cloud To upload it to Gemini. You can't access the transcript directly from the chat screen: you have to export the file first.
If you're going to use it often, it will come in handy. create a folder in Google Drive (for example, "Audios to transcribe") to keep everything organized. This way you can attach audios to Gemini in two taps and maintain a history of what you process.

Size and duration limits: what you should keep in mind
Regarding limits, it is important to understand two realities that coexist depending on the plan and its implementation: on the one hand, many users can Upload files up to 100 MB and process 10-minute audio files in the free version, with expansion up to three hours on payment plans (such as Gemini Advanced/AI Pro). It is also possible to send Up to 10 files in a single prompt, and even attach them in a ZIP file with up to 10 items.
On the other hand, there are guidelines and cases where a limit is reported. 20 MB when uploading audio files. If you encounter this restrictionTry compressing or trimming the audio with any simple editor (for example, an MP3 cutter or an online audio trimmer) and try again. Split the file In some parts it's usually a lifesaver if the recording is very long.
Prompts that work: from transcription to analysis
Once you attach the file, the key is to give Gemini a specific instruction. These are: useful prompts for different needs:
- "Transcribe this audio in its entirety" to obtain the full text with careful punctuation.
- "Transcribe and correct pronunciation errors or filler words" if the person speaks rapidly or repeats filler words.
- "Summarize the key ideas in cartoons" to get a quick outline with the main points.
- "Extract dates, tasks, and agreements mentioned" when you want to generate a follow-up list.
- "Indicate the fragments where 'delivery' is mentioned and their context" for thematic searches within the audio.
- "Generate a transcript and translate it into English/Spanish" if you need the content in another language.
Additionally, you can discuss the content: ask direct questions Questions like "What is this audio about?", "Are there any deadlines?", or "Who makes decisions in the conversation?", Gemini understands the context of the file and answers you with surprising accuracy.
