Technical Requirement Document (TRD)

Backend Technologies

They chose Node.js and Express.js for their speed and scalability in backend development. PostgreSQL was selected for its robust data management capabilities, essential for handling sensitive user data​​.

iOS App Development

Swift was the natural choice for iOS app development due to its efficiency and native compatibility. UIKit and Swift UI frameworks were used for developing a responsive user interface. Additionally, Firebase and Core ML were incorporated for functionalities like social authentication and machine learning on iOS devices​​.

Chatbot Integration

Recognizing the potential of AI in enhancing user interaction, shopdev planned the integration of GPT-3.5 Turbo and ChatGPT. This move was aimed at facilitating dynamic and intelligent avatar conversations, tapping into OpenAI's advanced language processing capabilities​​.

Cloud Deployment and Security

The TRD recommended using DigitalOcean Functions for efficient serverless operations and Spaces CDN for optimized content delivery. DigitalOcean's Cloud Firewalls were chosen to ensure robust protection against external threats, a crucial aspect of securing web applications​​.

User Analytics and Compliance

The incorporation of Google Analytics was planned for insightful user behavior tracking. Compliance with GDPR and CCPA was integral to their strategy, focusing on data encryption and a transparent privacy policy​​.

ML Modules in the Technical Requirement Document (TRD)

1. ChatGPT for Dynamic Conversations and Insights Extraction

Functionality

ChatGPT stands at the forefront of our technology stack. Leveraging OpenAI's GPT-3.5 Turbo model, it facilitates engaging, context-aware conversations with users. The module excels in processing natural language, allowing the AI avatar to communicate effectively and respond with a high degree of relevance and personalization.

Advanced Applications

Beyond standard conversations, ChatGPT is adept at interpreting visual content and textual data. It can analyze images to extract pertinent information and interpret PDF documents, turning unstructured data into actionable insights. This feature enriches user interactions, enabling the AI avatar to discuss a wide range of topics and provide informed responses based on external data sources.

2. Tortoise TTS (Text-to-Speech) for Lifelike Voice Generation

Purpose

The Tortoise text-to-speech model plays a pivotal role in giving voice to the AI avatar. It converts textual responses generated by ChatGPT into natural-sounding speech, enhancing the realism of the avatar.

Customization and Quality

This module is known for its ability to generate high-quality, lifelike voice output. It offers customization options, such as adjusting tone and speech rate, allowing the avatar's voice to match its personality and the context of the conversation.

3. Apple Voice Recognition for Seamless Voice-to-Text Conversion

Integration

Apple's voice recognition technology is integrated to facilitate a two-way communication channel. It efficiently translates user's spoken words into text, enabling the appto understand and process user commands or queries spoken aloud.

Accuracy and Speed

Known for its high accuracy and speed, Apple's voice recognition ensures that user inputs are captured correctly and promptly, contributing to a fluid and intuitive user experience.

4. Wav2Lip for Synchronized Lip Movements

Objective

The Wav2Lip model is critical in syncing the avatar's lip movements with the spoken voice. This synchronization is essential for creating a believable and immersive interaction experience.

Realism Enhancement

By accurately matching lip movements to the generated speech, Wav2Lip adds a layer of realism to the avatar, making conversations feel more natural and engaging. This visual coherence between speech and movement is crucial for maintaining the illusion of a live, interactive entity.
