Usage Calculation
Only the audio duration that starts to participate in Speech-to-Text is counted for usage statistics.
For multi-stream input from the host, the usage duration of each stream is summed up for billing.
Note:
When initiating a Speech-to-Text task for a TRTC room, the system assigns a virtual robot to act as an audience member. This robot subscribes to the required audio/video streams, and fees are calculated based on the duration of streams received by the robot. For details, refer to Billing of Audio and Video Duration.
Durations for each day are calculated in seconds for each application (SDKAppID) and then converted to minutes (rounded up to the nearest minute) for billing.
Billing Example
User A wants to use the Speech-to-Text service, so they need to purchase an RTC-Engine Monthly Package (Light/Standard/Pro version) to use this capability. Suppose they purchase the Engine Light version in February 2025 and enable the Speech-to-Text service. On February 1, the usage is 100 minutes.
On February 2, 2025, the Speech-to-Text fee that User A needs to pay is as follows:
Speech-to-Text fee = 100 (minutes) × 0.02 (USD) = 2 USD. This fee will be deducted around 10 AM on February 2, 2025.
