Hi Frederik Gysel,
Greetings from Syncfusion support.
We are currently using the Web SpeechRecognition API for the Speech-to-Text functionality. Unfortunately, this API does not provide built-in support for handling punctuation marks such as commas or sentence breaks.
Some punctuation behavior can depend on the language being spoken and the browser’s underlying speech engine, which may vary across different platforms. Because of these limitations, we are unable to offer consistent punctuation support at this time.
If you need more details, you can refer to the official Web Speech API documentation, which explains the current capabilities and constraints.
Please let us know if you have any further questions or need assistance with alternative approaches.
Regards,
Kirupa.
