I am thinking about creating new app with voice recognition, but please for advice: It is good step to choose google voice recognition or its better to choose another way? For example BING API, etc?
Now, it is possible to use VR and it cost - nothing, but what in the future? It looks that soon Google VR will be not available free, its true? https://cloud.google.com/appengine/pricing
If Google VR will not be free - do you have experience with other free services than google VR?
