Alibaba Cloud Intelligent Speech Interaction 3-Month Free Trial for New Users (2 hours of recorded-file recognition per day)

3-month free trial for new users: recorded-file recognition can transcribe 2 hours of audio free every 24 hours, and one-sentence recognition and real-time speech recognition each come with 2 free concurrent channels

Official FAQ "What are the limits of the trial edition" verbatim: one-sentence recognition and real-time speech recognition handle at most 2 recognition requests at the same time; recorded-file recognition: during the 3-month trial period, new users can transcribe 2 hours of recorded files free every 24 hours, and after the free quota is used up you can keep trying after another 24 hours. The real-time speech recognition trial edition provides 2 free concurrent channels, valid for 3 months, and 200 concurrent channels are provided by default after commercial activation. Official billing-methods doc (updated 2026-09-22): Intelligent Speech Interaction services must be activated before use, and some services offer new users a 3-month free trial; when the trial ends or the specs no longer meet your needs, you can upgrade to the commercial edition.

⚠️Only some services offer a trial; go by the "Service management and activation" page in the console. The official docs stress that after upgrading to the commercial edition you cannot switch back to the trial edition, and the only way to keep using it free is a new account, so do not click "Upgrade to commercial edition" by accident during the trial. The trial has only 2 concurrent channels, which suits personal transcription and small-scale debugging. Validity is 3 months from activation. Activating cloud products on an Alibaba Cloud account usually requires real-name verification.
