Billing rules

Intelligent Speech Interaction must be activated before use. New users receive a 3-month free trial. When your trial ends or no longer meets your business needs, you can upgrade to a commercial plan. The commercial plan offers two billing methods:

With the resource plan (subscription) method, you upgrade to the commercial edition and purchase a resource plan to offset usage charges.
With the pay-as-you-go (postpaid) method, billing starts automatically after you upgrade to the commercial edition and begin using the service.

Resource pack (pre-paid)

Purchase discounted resource plans for specific billable items. Usage is first deducted from the resource plan. This pay-in-advance model is ideal for stable, predictable usage.

A subscription package is valid for 1 year. You can stack multiple packages, but they cannot be renewed or upgraded. Usage is updated the day after purchase. Once the package quota is exhausted, service calls are billed at the pay-as-you-go rate.

Billing examples

Example 1: If usage is less than the minimum billing unit, the fee is calculated as: (usage ÷ minimum billing unit) × unit price
- For example, the fee for processing 30 minutes of audio with audio file recognition is: 0.5 hours × 2.50 CNY/hour = 1.25 CNY.
- For example, the fee for processing 1,000 characters with long-text speech synthesis is: (1,000 characters ÷ 10,000 characters) × 3.00 CNY = 0.30 CNY.
Example 2: For pay-as-you-go, the entire daily usage is billed at the tiered discount price corresponding to the total usage for that day.

For example, if the short sentence recognition service processes 500,000 calls in one day at a tiered discount price of 3.00 CNY per 1,000 calls, the total daily fee is: 500 × 3.00 CNY = 1,500.00 CNY.
