Is it possible to list the Google APIs in the Artificial Intelligence, especially in the Voice recognitions, comparison, analytics etc?

Yes, it’s possible but I find issues with the accuracy. I am currently using Marsview API’s for speech analytics, tone analytics, custom build and speech to text. Marsview APIs provided me with a Cloud containerized full suite API of language, tone and empathy analyzer. Added to this I was able to rapidly customize my own API solution according to my requirement with an impressive accuracy. I believe it would be a great helping hand to many developers like me because of its easy integration, public cloud and private on-premise deployments.
