Current behavior

Hello, since the silence threshold property gets ignored, i've been set the "end" listener callback, so that it triggers "start()" again. this way i managed to achieve continuous voice transcription on android 14.

However, this isn't working on my android 10 and android 12 devices:

• if i don't speak for a few seconds after start(), the recognition stops after a few seconds, without triggering any listener;

• if i speak, if i stop briefly, the "end" listener never triggers, unless i intentionally stop the speech transcription. it just stops after "speechend".
  I tried moving the logic to the "speechend" listener, but after a while it just gets stuck on "speechstarted" or "start" listeners.

• i tried adding the following code to androidmanifest.xml, per https://stackoverflow.com/questions/71505916/speechrecognition-does-not-work-on-android11:
  "

"

• also i tried commenting out every instance of "RecognizerIntent.EXTRA_PARTIAL_RESULTS", "RecognizerIntent.EXTRA_SEGMENTED_SESSION", "RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS", "RecognizerIntent.EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS",
  per https://stackoverflow.com/questions/71967536/why-has-speechrecognizer-suddenly-stopped-working.

may i get some context on this matter please? Thank you, and Kind Regards.

Expected behavior

during silence, the "end" listener should trigger before the recognition acutally ends

Reproduction

i was kindly allowed to skip the reproducible example

Steps to reproduce

1. put logic in "end" listener so that is isListening() === false, start() will be called;
2. as user requests recognition service, init listeners
3. and call start() method.

Thank you fopr reporting that. I was able to fix this. The end listener should now also be fired if no text was recognized. Please give this dev release a try:

npm i @capawesome-team/capacitor-speech-recognition@7.3.1-dev.dc9b0cb.1747921207

[ChristopherL-creator]

Thank you so much for your availability! i'll try it out and tell you how it goes

[ChristopherL-creator]

it seems to be working! but it only accepts english sentences, is there anything i can do about that?

[ChristopherL-creator]

nevermind, it was typo on my part, when setting the language in start(). Great job, thank you so much, and have a nice day

[robingenz]

You're welcome! Thank you for testing. I will publish a new release tomorrow.
