- Currently, the 3-month trial period is free of charge. The billing policy may be subject to change. Follow the latest bulletins on our official website.
- You will have unlimited usage of the short sentence recognition, real-time speech recognition, and speech synthesis services on each calendar day if the number of concurrent calls does not exceed two.
- The recording file recognition service can recognize recording files with a maximum total duration of 2 hours on each calendar day.
- If you require more than two concurrent calls or want to recognize recording files longer than 2 hours in length on each calendar day, upgrade the corresponding service to Commercial Edition.
- The default billing method of Commercial Edition is pay-as-you-go.
- The service in Commercial Edition is billed based on your actual service usage per calendar day. No free quota is available. No fee will be charged if you do not use the service. The system automatically calculates and bills your whole daily usage at 24:00 (UTC+8) every night. Bills may be generated with a certain delay.
- Detailed information:
- For services billed based on duration, the system accumulates the duration of the speech processed by each service call. The duration is measured in seconds and rounded down. For example, if the speech processed by a service call is 22.8 seconds in length, the duration is recorded as 22 seconds.
- For services billed based on the number of service calls, failed calls are not counted.
- All usage on each calendar day is billed at the tiered price for the total usage calculated at 24:00 on that day. For example, if the short sentence recognition service is called 500 thousand times in a day, the charge for that day is calculated as follows: 500 × USD 1.20 = USD 600.00. In this example, USD 1.20 is the tiered price that corresponds to the usage of 300 to 999 thousand calls.
- The number of calls to the speech synthesis service is calculated based on the number of UTF-8 encoded characters passed in each service call. Each Chinese character, English letter, or full-width or half-width punctuation mark is counted as one valid character. If 100 or fewer characters are passed in a service call, one call is billed. If 101 to 200 characters are passed in a service call, two calls are billed. If 201 to 300 characters are passed in a service call, three calls are billed. A maximum of 300 characters can be passed in one service call at a time. For example, two calls are billed for a service call with 102 characters, and three calls are billed for a service call with 201 characters.
The concurrency level refers to the number of service calls that the server is processing simultaneously for an Alibaba Cloud account.
The processing of a service call usually takes a certain amount of time to complete. For example, if you initiate a speech recognition request and continuously send speech data to the server for processing, the concurrency level is 1. If you initiate a new speech recognition request before the previous request is completed, the server simultaneously processes two requests for you. In this case, the concurrency level is 2.
