AI-Driven Voice Communication Integration

This project implements an AI-driven voice communication integration using the Twilio Programmable Voice API, Next.js, and PostgreSQL. It includes features such as real-time voice communication, transcription storage, sentiment analysis, and a dashboard to visualize interaction data.

Features

• Real-time voice communication using Twilio Programmable Voice API
• Transcription of voice interactions stored in PostgreSQL
• JWT authentication for securing API endpoints
• Real-time speech sentiment analysis using Google Cloud Natural Language API
• Dashboard UI to visualize transcripts and interaction data

Prerequisites

• Node.js (v14 or later)
• PostgreSQL database
• Twilio account with Programmable Voice API access

Setup

1. Clone the repository:

git clone [https://github.com/your-username/voice-communication-integration.git](https://github.com/your-username/voice-communication-integration.git)

2. Install dependencies:

npm install
# or
yarn install
# or
pnpm install
# or
bun install

3. Set up environment variables: Create a .env.local file in the root directory and add the following variables:

DATABASE_URL=""
AUTH_SECRET=""
GOOGLE_CLIENT_ID=""
GOOGLE_CLIENT_SECRET=""
TWILIO_ACCOUNT_SID=""
TWILIO_AUTH_TOKEN=""
NEXTAUTH_URL=""
EMAIL_ADDRESS="" # I made use of Google third party apps to send emails using nodemailer
APP_PASSWORD=""
TWILIO_PHONE_NUMBER=""

4. Set up the database:

npx prisma generate
npx prisma db push

# or

bunx prisma generate
bunx prisma db push

5. Run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

Open http://localhost:3000

Usage

1. Sign up or log in to the application.
2. Navigate to the dashboard to view transcripts and sentiment analysis.
3. To make a voice call, use the Twilio API to initiate a call to your application's voice endpoint.

API Endpoints

• /api/auth/*: Authentication endpoints (handled by NextAuth.js)
• /api/twilio/voice: Handles incoming voice calls
• /api/twilio/initiate-call: Handles outgoing calls (Not properly working yet)
• /api/transcripts: Fetches stored transcripts
• /api/transcription-callback: Handles the transcription of recorded calls and stores the transcript in the database
