hi @nameless-web-master

Why this happens:
Many speech-to-text libraries (like expo-speech, react-native-voice, SpeechRecognition API) emit partial results while you speak, then a final result at the end. If you append every event result instead of only accepting final ones, you’ll get duplicate words.

How to fix:

• Check which speech recognition library you are using.
• Inspect your event handling:
  • Only update your state/input field when the event type is “final” (not “partial” or “interim”).
  • If updating on every result, clear the previous input before appending new text.

Example fix with react-native-voice

onSpeechResults = event => {
  // Use only event.value[0], which is the final result
  this.setState({text: event.value[0]});
};

Example with expo’s SpeechRecognition (simplified pattern):

SpeechRecognition.onresult = event => {
  if (event.isFinal) {
    setInput(event.results[0][0].transcript);
  }
}

Other tips:

• Make sure you don’t accumulate old results in your state.
• Make sure your callback only sets the current transcript, not adds to previous transcripts.
• Test on multiple devices/iOS versions in case it’s device-specific.

Summary:
Words are duplicated because interim/partial results are being combined with final results. Change your event handler to use only the “final” result, reset the input each time, and test again.
