Note

  • Free trial

    The following rules on the use of the free trial have been applied since March 1, 2020:

    • The trial is free of charge. The billing policy may be subject to changes. Follow the latest bulletins on Alibaba Cloud international site (alibabacloud.com).

    • You 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. Intelligent Speech Interaction provides you with a three-month free trial for these services.

    • The recording file recognition service can recognize recording files with a maximum total duration of 2 hours on each calendar day. Intelligent Speech Interaction provides you with a three-month free trial for the service.

    • Intelligent Speech Interaction does not provide a free trial for the long-text-to-speech synthesis service. If you need to use this service, activate Commercial Edition.

  • Commercial Edition

    The following rules on the use of Commercial Edition have been applied since June 10, 2019:

    • If you require more than two concurrent calls of recording file recognition or need 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. After you purchase a resource plan, the billing method automatically changes to subscription. All fees incurred for your subsequent service calls are deducted from the subscribed resource plan. When all the resources in the resource plan are used up, the billing method automatically changes to pay-as-you-go again.

    • Services in Commercial Edition are billed based on your service usage per calendar day. No free quota is available. No fee is charged if you do not use the services. The system automatically calculates and bills your whole daily usage at 24:00 (UTC+8) every day. Bills may be generated with a specific delay.

    • We recommend that you do not downgrade services in Commercial Edition to the free trial. After the downgrade, the services become unavailable because the number of available concurrent calls is decreased to 0.

    • 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 that is 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 by using the following formula: 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.

Billing details of additional features and resources

  • Extra concurrent calls

    Extra concurrent calls that are beyond 200 concurrent calls

    CNY 100 per call per month

    CNY 1,000 per call per year

    Note

    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. 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. As a result, the concurrency level becomes 2. In most cases, the processing of a speech request lasts for a period of time.

  • Self-learning platform

    • After technology upgrades, Alibaba Cloud allows you to create custom linguistic models on the self-learning platform for free.

    • You can create a maximum of 10 custom linguistic models.

    By using custom linguistic models, you can optimize the recognition of speech data in business-specific subfields to improve speech recognition accuracy.

  • Speech synthesis speaker customization

    The price of this service varies with the business scenarios, data volume, speaker types, and possession of intellectual property rights. Therefore, no unified quotation is offered.

    If you need to use this service, contact us at nls_support@service.aliyun.com. The relevant responsible person will follow up and offer a quotation after a detailed discussion with you.
