What does Sounder API do?

The Sounder API simplifies the transcription process, offering a reliable, scalable, and secure solution for integrating transcription capabilities into your applications.

How does Sounder API work?

When a user uploads a[n] [audio] file to our Audio Data Cloud, we automatically run it through a series of proprietary models and processes to get the output of a transcript. Our advanced transcription engine utilizes cutting-edge speech recognition technology to convert spoken language into text. This process involves analyzing the audio input, identifying spoken words, and generating accurate transcriptions.

What languages does Sounder API support?

Sounder API is presently equipped with English and Spanish dual language support capabilities.

How much does it cost to use Sounder API?

At $0.25 per hour of audio transcribed, our transcription technology is priced at a fraction of the cost compared to other tools available in the market. Pricing for our additional API capabilities is coming soon. We are required to charge at least $0.25 every time a user uploads an audio file via API. This means that audio files that are less than 60 minutes in length will still cost $0.25 to transcribe.

Is there a free trial available before I make a payment commitment?

No, there is not currently a free trial available, but at $0.25 per hour of audio transcribed our pricing is very competitive and we are deeply committed to customer satisfaction.


Transcription: not simply a nice to have, but a need to have.

Making your podcast universally accessible? That's a win-win.
