Google's Speech Recognition API Usage Limits

Question

I'm using speech recognition api of Google. I created a wrapper in Java (like this: http://pastebin.com/zJEhnJ74); all works quite fine but sometimes I receive http 403 or http 500 so I'm thinking that there are some day limits.

I know that this is not an official API but someone knows the limit of the service (max requests for day, max length of audio file, and so on)?

Answer 1

There is a maximum time limit for an individual Speech Recognition 'session' which seems to be around 60 seconds. That means that you can have Google process a sentence but then you need to end that session and start a new one.

If you can use JavaScript then you should use the SpeechRecognition API - take a look at a simple example that I wrote in this tutorial
