Why AskSia
What makes AskSia a strong tool to transcribe MP3 files.
MP3 files come from everywhere: podcast downloads, voice memos exported as MP3, recorded calls, old archives, and lecture rips. AskSia handles every variant without asking you to clean up the file first.
Accurate on real-world MP3 audio
Lots of MP3s are compressed, recorded on a phone, or saved at low bitrate. AskSia stays usable in those conditions and reaches 95% or higher accuracy on clear audio with context-aware processing for technical vocabulary, names, and academic terms.
95%+ on clear audio
Speaker labels for every voice
AskSia identifies up to 10 distinct speakers in a single MP3, color-codes their turns, and timestamps each one. Rename them after the fact, for example 'Host' and 'Guest', and the change applies to the whole transcript.
Up to 10 speakers, renameable
An AI assistant on the transcript
Once an MP3 is transcribed, the side-panel AI assistant Sia helps you make sense of it. Ask for a summary, the timestamp where a topic was first mentioned, a list of direct quotes, or a quick quiz on the content.
