Title: Pass in custom request parameters to speechToText

Made it so that you can pass a an object which represents request parameters to the speech api. (allowing you to change language or audio file type for instance).

Also changed it so that access token is saved when ```getAccessToken``` is called. This makes it redundant to have to pass in an accessToken to speechToText function since you'll have either passed it through the constructor or called ```getAccessToken```.
