Ask HN: Is IBM Watson speech to text API so bad

Posted by bikash1999 on Monday August 07, 2017 @01:33AM
from the ask-hn dept.

I am have a requirement for converting speech to text using a prerecorded audio file. I am planning to use IBM Watson API (I have license for unlimited api request) but results are very bad and is hardly accurate. Whereas the same file if I use google speech to text gets me almost accurate.

So I feel not using IBM Watson API.

Below is a test for Speech to Text using IBM watson https://speech-to-text-demo.mybluemix.net/

Google Speech to Text https://www.google.com/intl/en/chrome/demos/speech.html

Any suggestions or experience around it??

I did some experimenting with Watson and Google using podcasts, and Watson came out pretty well in the mix - https://dague.net/2017/06/12/comparing-speech-recognition-fo... and https://dague.net/2017/06/13/visualizing-watson-speech-trans.... I haven't done systematic analysis with a lot of data points yet.

You can get per word confidence levels back from the Watson API if you ask for it, which is useful to know what parts it is sure about and what parts it is not.

Disclaimer: I work at IBM. But feel free to reach out at [email protected] if you want some help debugging on the Watson STT side.

Why not use Google Speech API ?

I guess probably because OP has license for unlimited requests on Watson.
