Seems like you are using Speex to encode your sound data. This was experimental and i'm not sure if it is even properly supported by google anymore. Please switch to flac by setting $use_speex = 0; in the 'User defined parameters' section of the script. Also make sure you have an up to date version of it and enable SSL/TLS (recent versions have it enabled by default)

Seems like the API returns an empty JSON object. If its not a problem with your recording or with the API limits on the number of requests then only Google can answer why this fails.

I guess Google Speech API is no longer working and newest addition is Google Cloud Speech API.
