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

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??
