The Cloud Speech API is priced monthly based on the amount of audio successfully processed by the service, measured in increments rounded up to 15 seconds. Pricing tiers are based on the total amount of audio processed by the service per month.
These prices are now in effect (as of August 1, 2016) and noted in the table below.
|Feature||0-60 minutes||61+ - 1 million minutes|
|Speech Recognition||Free||$0.006 / 15 seconds*|
This pricing is for applications on personal systems (e.g., phones, tablets, laptops, desktops). Please contact us for approval and pricing to use the Speech API on embedded devices (e.g., cars, TVs, appliances, or speakers).
* Each request is rounded up to the nearest increment of 15 seconds. For example, three separate requests, each containing 7 seconds of audio, would be billed as 45 seconds (3 × 15 seconds) of audio.
Monthly usage is capped at 1 million minutes per month. For usage above 1 million minutes of audio per month, we would like to understand more about your needs, and may be able to build custom solutions. Please submit a Cloud Speech API Quota Request for your project.
