Engineering guide
For offline speech feature scope, use the sequence below to retain reproducible inputs, actions and exception evidence. This is an implementation method; actual interface names, commands and parameters depend on the target device and version documentation.
Implementation and exception checks
Swipe the table horizontally to view all columns.
| Step | Action and evidence | Exception handling |
|---|---|---|
| Audio input | Freeze input format, microphone routing and authorized test recordings | Distinguish absent audio, format errors and recognition failures |
| Recognition events | Check wake events, ASR result fields and completion/cancellation behavior | A wake event is not successful speech recognition |
| Synthesis and playback | Use fixed text to check TTS output, audio routing, cancellation and release | Returned audio does not establish speaker playback; test each capability offline |
What inputs are needed before starting?
Target platform, audio path, SDK licenses, authorized recordings, vocabulary or fixed text, and network constraints. Check document versions and availability first and retain missing items as unresolved inputs.
How should delivery and acceptance be defined?
On the target device test audio input, recognition events, synthesized output and audible playback separately; record online, offline and cancellation results. A TTS case does not establish ASR or wake-word capability; integration does not establish recognition performance in every setting.
Enterprises in Hefei, China, can submit these inputs for remote review. Agree prototype integration, sample shipment, site work and associated costs for the specific project.
Review the service scope and submit the project inputs before agreeing on development and delivery. Original Chinese service scope
