Python: Keyword not being recognised from a .wav file

[Jack Johns]

I'm trying to detect the keyword temperature from a recording of me only saying the phrase temperature (there are no other words present). Originally I used the keyword hello and it worked fine but whenever I try with any other word it does not. My current code is as follows:

import pocketsphinx as ps
import requests
import json
import sys, os

model_path = ps.get_model_path()
data_path = ps.get_data_path()

# Call to API
def get_temperature():
    headers = {
        'accept': 'application/json',
        'x-api-key': 'REMOVED'
    }

    response = requests.get(url=TEMPERATURE_URL, headers=headers)
    print("Response Code: ", response)

    temperature_data = response.json()
    print(temperature_data)
    temp = temperature_data[0]["value"]
    return temp

print("start")
while True:
    speech = ps.AudioFile(lm=False, kws='keyphrase.list', kws_threshold=1e-1)
    for phrase in speech:
        print("--------------------------------------------------------------")
        print(phrase.segments(detailed=True))
        print(phrase)
        if phrase.__eq__('temperature '):
            print("if equal")
            temperature = get_temperature()
            print("Temperature: ", temperature)

The contents of my keyphrase.list file is:

temperature /1e-1/

It currently starts and runs but doesn't detect anything. Any help would be much appreciated.

Try threshold 1e-20, 30, 40

I replied you on stack overflow already.

Hi, thanks for the reply. I've just tried this and it didn't change anything. Have you got any other ideas?
