Caching

TTS responses are globally cached to improve performance. You can set Cache-Control to no-cache to skip the cache.
Following parameters are hashed as the cache key:

  • text
  • voice
  • speed
  • metadata
  • effect
  • bitrate
  • sampling_rate
  • output specified by the Accept header

Cache is missed when any of these parameters change.
