Improve Android speech recognition with additional context

Question

As I understand Android API uses google speech recognition service for speech to text.

I've learned API and I see it's pretty simple and just converts voice to words array.

Is any way to improve the recognition, I mean, if I know the context can I send some parameters to the service in order to improve the recognition?
Or alternatively is any other speech recognition service which can be used for this purpose?
Thanks in advance.

No

Most SaaS service do not provide customization capabilities because it requires them to tune things internally. They usually work with predefined configuration.
