# Import an audio file with multiple speakers
multiple_speakers = sr.AudioFile("multiple-speakers.wav")

# Convert AudioFile to AudioData
with multiple_speakers as source:
    multiple_speakers_audio = recognizer.record(source)

# Recognize the AudioData
recognizer.recognize_google(multiple_speakers_audio)

one of the limitations of the speech recognition library is that it doesn't
recognise different speakers and voices it will just return it all as one block 
of text

# Import audio files separately
speakers = [sr.AudioFile("s0.wav"), sr.AudioFile("s1.wav"), sr.AudioFile("s2.wav")]

# Transcribe each speaker individually
for i, speaker in enumerate(speakers):
    with speaker as source:
        speaker_audio = recognizer.record(source)
    print(f"Text from speaker {i}: {recognizer.recognize_google(speaker_audio)}")

Text from speaker 0: one of the limitations of the speech recognition library
Text from speaker 1: is that it doesn't recognise different speakers and voices
Text from speaker 2: it will just return it all as one block a text

Jeśli mowa jest trudna do zrozumienia dla człowieka, API również będzie miało trudności

# Import audio file with background nosie
noisy_support_call = sr.AudioFile(noisy_support_call.wav)

with noisy_support_call as source:
    # Adjust for ambient noise and record
    recognizer.adjust_for_ambient_noise(source, 
                                        duration=0.5)
    noisy_support_call_audio = recognizer.record(source)

# Recognize the audio
recognizer.recognize_google(noisy_support_call_audio)
