Thank you very much for using our services.
We would like to inform you that we will be changing the calculation method for AmiVoice API usage fees as follows.
The effective date will be Wednesday, October 1, 2025.

Usage Amount
・Usage refers to the length of audio data sent to the API endpoint that AI determines to be speech segments and that is subject to billing. Silence segments are not included in the usage.
- Usage for each engine is calculated in milliseconds. When calculating monthly usage fees, any fractional seconds is rounded down.

About fee calculation
・The usage fee for each engine is calculated by subtracting the free usage limit (3,600 seconds) from the usage amount for each engine, and then multiplying it by the unit price (excluding tax) for each engine.
・The usage fee for each engine is calculated in units of 1 yen. Any amount less than 1 yen will be rounded up or down.
・The usage fee for the current month (excluding tax) will be the total of the usage fees for each engine. If the total amount (excluding tax) is less than 50 yen, no charge will be made.
・The actual consumption tax is calculated by multiplying the usage fee (excluding tax) for that month by the consumption tax rate. Any amount less than 1 yen will be rounded down.

Major changes
The main differences in this change are:
・If the usage fee (excluding tax) for each engine is less than 10 yen, there will be no charge.
→If the total amount (excluding tax) is less than 50 yenThere is no charge.
・The fee is calculated by multiplying the "usage" for the current month by the unit price of each plan (rounded down to the nearest yen).
→Usage fees for each engine are calculated in 1 yen increments.Any amount less than 1 yen will be rounded up or down.
