## TL;DR

The fix is in the event handler, not the API call. That gives you one final line per utterance instead of the streaming repeats.

## Steps

1. Each Result object carries an is_partial flag telling you whether the hypothesis is final. Only emit results where result.is_partial is False. The maintainer's example handler: class MyEventHandler(TranscriptResultStreamHandler): async def handle_transcript_event(self, transcript_event): results = transcript_event.transcript.results; for result in results: if result.is_partial is False: for alt in result.alternatives: ... handle alt.transcript here. That gives you one final line per utterance instead of the streaming repeats.

## When to use

You are seeing this: A user streaming audio through Amazon Transcribe got output with every partial hypothesis repeated: This. / This is / This is a / This is a te / This is a test.

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens
