Frequently asked questions
Is it accurate for fast-spoken Spanish?
Yes. Whisper handles fast natural speech well. For very fast speakers or overlapping voices, accuracy may drop slightly — just review the transcript in the browser and fix any errors before downloading.
Does it work for Mexican Spanish vs Castilian Spanish?
Yes. Whisper handles both equally well, plus Argentine, Colombian, Chilean, Peruvian, and other regional varieties. Vocabulary differences are usually transcribed correctly.
Can I get a Spanish blog post from a Spanish podcast?
Drop the podcast file, get the transcript, then use the AI Summary as a starting point. The summary, key points, and action items are all generated in Spanish automatically.
How do I record Spanish audio?
iPhone Voice Memos, Android voice recorder, Zoom recording, or any digital recorder. Save as .m4a or .mp3 and upload above. For phone calls, use call-recording apps that comply with your local laws.
