If you want to use Kaldi solution, follow this installation guide before you run pip install .

$ pip install .

Windows

TBD

Different audio sources

from speechtotext import SpeechToText

# Initialize the speech to text solution
stt    = SpeechToText()

# Speech to text from audiofile
record = stt.record_from_audiofile("test_record.wav")
text   = stt.translate(record)
print(text)

# Speech to text from a microphone phrase
stt.adjust_for_ambient_noise()
record = stt.record_from_microphone()
text   = stt.translate(record)
print(text)

Different recognition solutions

from speechtotext import SpeechToText
from speechtotext import SOLUTION_KALDI, SOLUTION_GOOGLE

# Initialize the speech to text solution
stt    = SpeechToText()

# Speech to text from audiofile using Kaldi solution
record = stt.record_from_audiofile("test_record.wav")
text   = stt.translate(record, solution=SOLUTION_KALDI)
print(text)

# Speech to text from audiofile using Google solution
record = stt.record_from_audiofile("test_record.wav")
text   = stt.translate(record, solution=SOLUTION_GOOGLE)
print(text)
