Different transcription for the same model streaming vs pre recorded.

[kholiavko-roman]

Some transcriptions are incorrect in real time, but when I tried to get transcription for the same recording on API playground - the transcription is correct for the same model. Is that a bug or the quality is worse just because of the real time?

My deepgram config:

{
      model:  'nova-2',
      interim_results: true,
      punctuate: true,
      no_delay: true,

      endpointing: 500,
      utterance_end_ms: 1300,

      encoding: 'mulaw',
      sample_rate: 8000,

      language: 'multi'
}
