This script allows you to use speech recognition to input a prompt, send the prompt to OpenAI to generate a response, and then use gTTS to convert the response to an audio file and play the audio file.

• You need to have a valid OpenAI API key. You can sign up for a free API key at https://beta.openai.com/.
• You need to install the following packages: openai, gTTS, pyaudio, SpeechRecognition, playsound. You can install these packages using pip install openai gTTS pyaudio SpeechRecognition playsound or use pipenv if you wish to contain a virtual environment.

1. Replace YOUR_API_KEY_HERE in the following line with your actual OpenAI API key: openai.api_key = "YOUR_API_KEY_HERE"
2. Run the script using python smart_speaker.py.
3. The script will prompt you to say something. Speak a sentence into your microphone. You may need to allow the program permission to access your microphone on a Mac, a prompt should appear when running the program.
4. The script will send the spoken sentence to OpenAI, generate a response using the text-to-speech model, and play the response as an audio file.

• You can change the OpenAI model engine by modifying the value of model_engine. For example, to use the "davinci" engine, set model_engine = "davinci".
• You can change the language of the generated audio file by modifying the value of language. For example, to generate audio in French, set language = 'fr'.
• You can adjust the temperature parameter in the following line to control the randomness of the generated response:

response = openai.Completion.create(
engine=model_engine,
prompt=prompt,
max_tokens=1024,
n=1,
temperature=0.7,
)

Higher values of temperature will result in more diverse and random responses, while lower values will result in more deterministic responses.
