PocketSphinx module not found despite installation

Question

I'm trying to use the PocketSphinx speech recognition engine in my Python script, but I keep encountering an error stating "missing PocketSphinx module: ensure that PocketSphinx is set up correctly." I've already installed PocketSphinx using pip, but it seems like Python can't find the module.

Here's the relevant portion of my code:

from pydub import AudioSegment
import os
# Function to convert OPUS files to WAV format
def convert_opus_to_wav(opus_file, output_wav_file):
    sound = AudioSegment.from_file(opus_file)
    sound.export(output_wav_file, format="wav")


# Function to transcribe audio using a speech-to-text service



import speech_recognition as sr

def transcribe_audio(audio_file):
    recognizer = sr.Recognizer()

    with sr.AudioFile(audio_file) as source:
        audio_data = recognizer.record(source)

    try:
        transcribed_text = recognizer.recognize_sphinx(audio_data)
        return transcribed_text
    except sr.UnknownValueError:
        print("Speech recognition could not understand audio")
    except sr.RequestError as e:
        print(f"Error with PocketSphinx recognizer: {e}")

    return ""  # Return empty string if transcription fails



# Directory containing OPUS files
opus_dir = "/Users/ethanhumphreys/Downloads/Blinkist SiteRip Audio Collection (August 2023)"

# Create a directory to store text files
output_dir = "/Users/ethanhumphreys/Documents/txt files"
os.makedirs(output_dir, exist_ok=True)

# Iterate through each OPUS file
for filename in os.listdir(opus_dir):
    if filename.endswith(".opus"):
        opus_file = os.path.join(opus_dir, filename)
        # Convert OPUS file to WAV
        wav_file = os.path.join(output_dir, os.path.splitext(filename)[0] + ".wav")
        convert_opus_to_wav(opus_file, wav_file)

        # Transcribe the WAV file
        transcribed_text = transcribe_audio(wav_file)

        # Write transcribed text to a text file
        text_output_file = os.path.join(output_dir, os.path.splitext(filename)[0] + ".txt")
        with open(text_output_file, "w") as text_file:
            text_file.write(transcribed_text)

I've verified that PocketSphinx is installed by running pip show pocketsphinx, which displays information about the installed package. However, when I run my script, I still get the error mentioned above.

Can anyone provide guidance on what might be causing this issue and how I can resolve it?
