Example 3 with SynthesizeSpeechResult

use of com.amazonaws.services.polly.model.SynthesizeSpeechResult in project myrobotlab by MyRobotLab.

the class Polly method cacheFile.

/*
   * Proxy works in 3 modes
   *    client - consumer of mrl services
   *    relay - proxy (running as cloud service)
   *    direct - goes direct to service
   * In Polly's case - 
   *    client - would be an end user using a client key
   *    relay - is the mrl proxy service
   *    direct would be from a users, by-passing mrl and going directly to Amazon with amazon keys
   * cache file - caches file locally (both client or relay)
