Watson speech to text: Invalid credentials error (Code: 401)

Question

I am trying to use the IBM Watson speech to text API/service in the following Python program.

import json
import os
import sys
from watson_developer_cloud import SpeechToTextV1

def transcribe_audio(audio_file_name) :
    IBM_USERNAME = "yourusername"  

    IBM_PASSWORD = "yourpassword"
    #what changes should be made here instead of username and password

    stt = SpeechToTextV1(username=IBM_USERNAME, password=IBM_PASSWORD)
    audio_file = open(audio_file_name, "rb")        
    json_file = os.path.abspath("america")+".json"; 
    with open(json_file, 'w') as fp:
        result = stt.recognize(audio_file,timestamps=True,content_type='audio/wav', inactivity_timeout =-1,word_confidence = True)
        result.get_result()
        json.dump(result, fp, indent=2)
    script = "Script is : "
    for rows in result['results']:
        script += rows['alternatives'][0]['transcript']
    print(script)
transcribe_audio("america.wav")

This code gave me an authentication error as mentioned in the title because IBM changed the authorization method from username + password to apikey very recently.

Could anybody tell me what changes should be made in this? And also how to generate the apikey on IBM Watson speech to text with username and password?

I am new to speech recognition, please let me know. Thanks in advance.

All the information you want is in the API documentation, including how to obtain the API Key - https://cloud.ibm.com/apidocs/speech-to-text?code=python
