Billing method

Last Updated: Jun 18, 2020

This topic describes the billing units and methods of Intelligent Speech Interaction in Alibaba Cloud. If you have any question about the pricing of the service deployed in a local environment, contact us through nls_support@service.aliyun.com.

Important notes

If you adopt the pay-as-you-go billing method, you are charged on a daily basis according to the standard billing rules of Alibaba Cloud. Your consumption on the current day will be billed on the next day. Therefore, you must keep your account balance sufficient to avoid overdue payments that may affect service use. You can also enable the Available Credit Alert and Daily Bill Alert features in User Center to ensure that you can stably use Intelligent Speech Interaction.

The free trial only supports a limited number of concurrent calls and provides recognition services for speeches with a limited duration. We recommend that you upgrade the target service to Commercial Edition for greater processing capability in a timely manner based on your business requirements. If any user repeatedly uses the free trial with multiple Alibaba Cloud accounts, Alibaba Cloud is entitled to directly take appropriate measures without notifying the user in advance. The user shall be responsible for the consequences that arise from the violation.

Billing rules

Trial Edition:

  • 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.

Commercial Edition:

  • 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:
    1. 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.
    2. For services billed based on the number of service calls, failed calls are not counted.
    3. 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.
    4. 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.

Calculation of concurrency level

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.

Self-learning platform

Free of charge during the promotional activity.
If you are a free trial user, Intelligent Speech Interaction allows you to create one custom speech training model and use it for free for one month. If you do not purchase the custom model at the end of the free trial period, you will not be able to use it any longer.
The unit price is USD 400 for each model per month.
You can purchase a maximum of 10 custom speech training models for an Alibaba Cloud account.
The system charges you a one-month fee on the day you purchase a custom model. The system will charge you on that day every month thereafter.
Example:

  • If you create a custom model on January 8, the system will charge you a monthly fee on that day. The system will charge you on the 8th of each subsequent month, for example, February 8 and March 8. If you delete the model on March 7, you will not be charged from March 8. However, if you delete the model on March 8, a monthly fee will still be deducted on that day.
  • If you create one custom model on January 8, you will be charged USD 400 on that day. If you create another model on January 20, which means you now hold two custom models, you will be charged another USD 400 on that day. On February 8, you will be charged USD 800 for the two custom models. If you delete one custom model on February 20, which means you now have only one custom model, you will be charged USD 400 on March 8.
  • If you create two custom models on January 8, you will be charged USD 800. If you delete one custom model on January 20 and create a new one on January 21, no extra fee will be charged.

If you do not have a custom model, you cannot enjoy the personalized customization service provided in the console.
