What goes into the cost of using SpeechKit

Using speech synthesis

The cost of using the SpeechKit API for speech synthesis is calculated from the total number of characters sent to generate speech from text over a calendar month (the reporting period).

The number of characters in a request is determined considering spaces and special characters. The cost of an empty request is equal to the cost of one character.

Using speech recognition

The cost of using the SpeechKit API for speech recognition is calculated from the length of audio files successfully processed by the service during the reporting period. The length of each audio file is measured in 15-second segments and rounded up.

Examples

  • You send a 37-second fragment for speech recognition. Your request is split into three segments: two that are 15 seconds long, and one that is 7 seconds long. The length of the last segment is rounded up to 15 seconds. The final cost of the request is calculated for 45 seconds.
  • You made two requests, for 5 and 8 seconds, respectively. The length of each request is rounded up to 15 seconds. The final cost of the request is calculated for 30 seconds.
