Transcription is slow where someone listens and types sentence by sentence
One hour of audio takes hours of listening and typing, rewinding where people talk over each other and keeping track of who said what.
Listening and typing, sentence by sentence.
01Turn speech into text
Send an audio or video file and get the text in segments with start and end times. Base is the quick, light tier.
1 credit a minute
Names and jargon spelt wrong all through the file.
02Pro corrects names and jargon
Pro rereads each part in context and corrects the text, which helps most on natural speech full of names and jargon.
2 credits a minute
Losing track of who said what.
03Labelled by speaker
Every segment carries a speaker label, and a score marks the parts heard unclearly, so you check only those.

Before you decide, you will want to know this
Every answer comes from the API documentation and the published measurement.
Do we still need to check the text?
Yes, especially dates, numbers and names. Every segment has an avg_logprob score; those below −0.15 are the ones to listen to again.
How long can a recording be?
Thai takes up to 30 minutes a request on either tier; split a longer file and send the parts in turn.
What about Thai mixed with English?
Yes, though English terms spoken with Thai pronunciation, such as Login, can come back as oddly spelt transliterations; check those terms.
How long does integration take?
One HTTP POST, with examples in curl, Python and JavaScript, and an open-source SDK for web and apps. Try it on the free credits before you write production code.
Can we get a tax invoice in our company’s name?
Yes. Request it from the credits page of your account after you pay.
