Setting up the environment
Before we proceed with the code, we need to set up our environment with the necessary tools. First, we will install Python and create a virtual environment. Python is a popular programming language that is easy to learn and use. A virtual environment is a way of isolating your project’s dependencies from other projects or system-wide installations. This will help you keep your project organized and prevent conflicts with other libraries or versions.
To install Python, you can download it from the official Python website. Make sure to choose the correct version for your operating system when downloading. When installing, be sure to check the option that adds Python to your system’s PATH. This will allow you to run Python from any directory in your terminal or command prompt.
To create a virtual environment, you can use the following commands in your terminal or command prompt:
$ mkdir voice_assist
$ cd voice_assist
$ python3 -m venv env
$ source env/bin/activateThese commands create a new project folder called voice_assist, navigate into the folder, create a new virtual environment named env, and activate the environment.
Next, we will install the required libraries such as OpenAI, Gradio, TTS, Whisper, etc. These libraries will help us with various tasks such as speech recognition, text-to-speech conversion, and generating responses with GPT-3.
OpenAI is a library that empowers us to interact with the OpenAI API and harness the power of GPT-3 for generating responses.
Gradio is an easy-to-use UI library that helps us build user interfaces for our AI voice assistant.
TTS is a library that enables text-to-speech conversion. This will allow our AI voice assistant to convert text into speech.
Whisper is a library that enables speech-to-text conversion. This will allow our AI voice assistant to convert speech into text.
To install these libraries, you can use the following command in your terminal or command prompt:
$ pip install openai gradio tts whisperFinally, we will set up the OpenAI API key and access GPT-3. The OpenAI API key is a unique identifier that allows us to use the OpenAI services such as ChatGPT API. To get an OpenAI API key, you need to create an account with OpenAI and request access from them. Once you have obtained the API key, you can set it up in your code using the following line:
openai.api_key = "YOUR_API_KEY"This line sets up the OpenAI API credentials required to access GPT-3.
Building the AI Voice Assistant
Now that we have set up our environment, we are ready to start building our AI voice assistant. We will use Gradio to create the user interface for our application. This will enable users to ask questions and receive responses from our AI voice assistant.
To create the user interface, we need to import Gradio and define two components: an input component and an output component. The input component is where the user can type or speak their query. The output component is where the user can see or hear the response from the AI voice assistant.
We can use Gradio’s built-in components such as SpeechToText or Textbox for the input component and Text or Audio for the output component. We can also customize the appearance and behavior of these components using parameters such as label, type, default_value, etc.
Here is how we can create the input and output components using Gradio:
import gradio as gr
# Create input component
input = gr.inputs.Speech
# Create output component
output = gr.outputs.TextThese two lines create a speech-to-text input component and a text output component for our user interface.
How to Create Function for AI Voice Assistant
Next, we need to define a function that will handle the logic of our AI voice assistant. This function will take the user’s query as an input and return a response as an output. The function will use Whisper to convert the speech input into text, OpenAI ChatGPT API to generate a response using GPT-3, and TTS to convert the text output into speech.
Here is how we can define the function for our AI voice assistant:
import openai
import tts
import whisper
# Define the function for the AI voice assistant
def voice_assist(query):
# Convert speech input to text
text = whisper.speech_to_text(query)
# Generate response using OpenAI ChatGPT API
response = openai.Completion.create(
engine="davinci",
prompt=text + "\n\nAI: ",
temperature=0.9,
max_tokens=150,
stop=["\n", "User:"]
)
# Convert text output to speech
speech = tts.text_to_speech(response["choices"][0]["text"])
# Return the response
return speechThis function takes the query parameter, which is the speech input from the user, and converts it into text using Whisper’s speech_to_text function. Then, it uses OpenAI’s Completion. Create a method to generate a response using GPT-3. The method takes several parameters such as engine, prompt, temperature, max_tokens, and stop. The engine parameter specifies which GPT-3 model to use. We use “DaVinci” which is the most advanced and capable model. The prompt parameter specifies what text to use as the input for GPT-3.
We use the text from the user’s query and add a new line and “AI: ” to indicate that the next line is the response from the AI voice assistant. The temperature parameter controls how creative or random the response is. We use 0.9 which is a high value that allows for more variability and creativity. The max_tokens parameter limits how many tokens or words GPT-3 can generate. We use 150 which is a reasonable limit for a short response.
The stop parameter specifies what tokens or words to use at the end of the response. We use “\n” and “User:” to indicate that the response should end when there is a new line or when the next line starts with “User:”. The method returns a dictionary with various information such as choices, which is a list of possible responses from GPT-3. We use the first choice as our response and access its text attribute to get the actual text of the response.
Finally, we use TTS’s text_to_speech function to convert the text output into speech and return it as our final output.
How To Launch AI Voice Assistant User Interface
The last step is to launch our user interface using Gradio’s launch method. This method takes several parameters such as inputs, outputs, and functions. The inputs parameter specifies what input components to use for our user interface. We use the input variable that we defined earlier. The output parameter specifies what output components to use for our user interface. We use the output variable that we defined earlier. The functions parameter specifies what functions to use for our user interface. We use the voice_assist function that we defined earlier.
Here is how we can launch our user interface using Gradio:
# Launch user interface
gr.Interface(fn=voice_assist, inputs=input, outputs=output).launch()This line launches our user interface with our voice_assist function, our speech-to-text input component, and our text output component.
Testing and Deploying the AI Voice Assistant
Now that we have built our AI voice assistant, we can test it locally and debug any errors. To test it locally, we can run our code in our terminal or command prompt and open the link that Gradio provides us. This will open a web page with our user interface where we can interact with our AI voice assistant.
We can ask any question or say anything to our AI voice assistant and see or hear its response. For example, we can ask “What is your name?” and get a response like “AI: My name is ChatGPT, nice to meet you.” or “How are you today?” and get a response like “AI: I am doing well, thank you for asking.” We can also ask more complex or specific questions such as “What is the capital of Nigeria?” or “How do I make an omelet?” and get appropriate responses from our AI voice assistant.
We can also check if there are any errors or bugs in our code or logic by looking at the terminal or command prompt where we ran our code. If there are any errors or exceptions, we can see them in the terminal or command prompt and try to fix them accordingly.
To deploy our AI voice assistant online, we can use Gradio’s share method. This method allows us to share our user interface with anyone on the internet. The method takes a parameter called to share, which is a boolean value that indicates whether to share the user interface or not. If we set it to True, Gradio will generate a unique URL for our user interface and display it in the terminal or command prompt. We can copy and paste this URL and send it to anyone who wants to try out our AI voice assistant.
Here is how we can deploy our AI voice assistant online using Gradio:
# Deploy user interface online
gr.Interface(fn=voice_assist, inputs=input, outputs=output, share=True).launch()This line deploys our user interface online with our voice_assist function, our speech-to-text input component, and our text output component. It also generates a unique URL for our user interface and displays it in the terminal or command prompt.
