Error Handling
Manage permissions and recognition failures gracefully.
Common Errors
Most errors are related to browser permissions or the Web Speech API's strict requirement for secure contexts (HTTPS).
Microphone Access Denied (NotAllowedError)
User blocked the permission prompt. You must show UI instructing them to re-enable it in settings.
No Speech Detected (no-speech)
Engine received audio but couldn't identify words. Usually background noise or silence.
Handling Strategy
javascript
1voice.start().catch((error) => {
2 if (error.name === 'NotAllowedError') {
3 alert("Please allow microphone usage!");
4 } else if (error.name === 'NotSupportedError') {
5 alert("Please switch to Chrome or Edge.");
6 }
7});
