Checking Usage and Billing

You can check API usage, billing information, and download invoices on the MyPage. The usage refers to the length of billable audio data sent to the API, which is the detected speech segments. For information on speech segments, please see Speech Detection and the tech blog article "What is speech segment detection?".

Usage of This Month​

You can check this month's usage on the MyPage TOP (Dashboard) and the Confirmation of Usage Fees page. The usage is aggregated by the following items, and the "Usage" figures include the free usage quota:

  • Speech recognition engine type
  • Logging or no logging (logging for "ログ保存あり", no logging for "ログ保存なし")
  • Synchronous HTTP / WebSocket (not specified) or Asynchronous HTTP

The aggregation is performed hourly, and the usage shown on the page is the amount that has been aggregated as of the date and time indicated. Due to the system's nature, there is a time lag between when the API is used and when the usage is aggregated, so even if speech recognition is completed before the aggregation time, it may not be reflected in the immediate aggregation. Also, aggregation by Usage Aggregation Tag cannot be confirmed in "Usage of This Month".

If you have a coupon, you can apply it from this screen. Please proceed with the [Apply Coupon] button on the screen.

Usage Details​

On the Confirmation of Usage Fees page, you can check the billing amount for each month up to the previous month and the details of the billing amount. The aggregation is performed by the following items, and the "Usage" figures include the free usage quota:

  • Speech recognition engine type
  • Logging or no logging (logging for "ログ保存あり", no logging for "ログ保存なし")
  • Synchronous HTTP / WebSocket (not specified) or Asynchronous HTTP

For aggregation by Usage Aggregation Tag, please see the CSV Output of Speech.

Invoice Download​

You can download invoices for the months displayed in "Usage Details". If there is no billing for usage, invoices cannot be downloaded.

CSV Output of Speech​

You can export the details of speech volume and usage fees (excluding tax) for the months displayed in "Usage Details" in CSV format. The aggregation is performed by the following items, and the "Speech Volume" figures include the free usage quota:

  • Speech recognition engine type
  • Logging or no logging (logging for "ログ保存あり", no logging for "ログ保存なし")
  • Synchronous HTTP / WebSocket (not specified) or Asynchronous HTTP
  • Usage Aggregation Tag

For aggregation values of speech recognition requests without a Usage Aggregation Tag set, the account ID is listed in the column where the Usage Aggregation Tag would be written.

Regarding usage fees, if there are speech recognition requests with Usage Aggregation Tags set, subtotals for each engine plan (combinations of speech recognition engine type, logging or no logging, and whether it's Asynchronous HTTP or not) are output, and amounts per Usage Aggregation Tag are not displayed. If the speech volume for each engine plan falls within the free usage quota and no usage fee is incurred, the subtotal row for that engine plan's amount is not output.

The usage fee (excluding tax) is calculated as follows:

  1. Calculate the subtotal of speech volume (milliseconds) for each engine plan, divide by 1000 to get the speech volume (seconds). Decimal points are truncated.
  2. Subtract the free usage quota from 1. If the value becomes zero at this point, the subtotal for that engine plan is not output.
  3. Multiply 2 by the unit price (excluding tax) of the engine plan. Round off to the nearest whole number.
