Available in Classic and VPC
You can create batches to process multiple speech recognition tasks at once. Once created, a batch automatically runs after a certain period, recognizing audio from media files located in the specified path, generating recognition result files and execution result files.
Note
- Batch charges are applied per input file.
- The execution result file (CSV) is generated every 10 tasks.
- If fewer than 10 tasks exist, an execution result file is generated when no additional tasks are processed for a certain time.
- Execution result files include:
- Task order
- Input file / result file names
- Recognition duration
- Task start / completion time
- Execution result
The Batch menu allows you to create and manage batches.
