LangHelper

Introduction to the LangHelper Project

LangHelper is an innovative project aimed at enhancing language learning through advanced speech interaction technologies. It combines the power of AI with user-friendly features, making language learning adaptable and engaging for a diverse range of users. Below outlines its features, installation process, and mission in detail.

Features of LangHelper

1. Talk to ChatGPT
   LangHelper provides conversational engagement with ChatGPT, coupled with vocal interactions. It supports a variety of speech types and accents, leveraging the expansive VCTK corpus, which includes hundreds of distinct accents. This makes language practice more authentic and versatile. Future support for additional platforms like Azure and iFlytek is anticipated. Users also have the option to converse with personalities such as Barack Obama or Taylor Swift through AI-simulated voices. Additionally, developers can integrate their Text-To-Speech (TTS) models via an available interface.

2. Speaking Assessment
   To aid language learners in improving their pronunciation, LangHelper incorporates two assessment APIs, speechsuper and iFlytek. These tools offer reliable pronunciation scoring, making it especially beneficial for users preparing for exams like IELTS and TOEFL. The system is continuously improving, open to integrating more sophisticated algorithms in the future.

Installation Instructions

LangHelper can be installed without hassle on Windows systems. The essential components include:

• ChatGPT and LangHelper Applications: Both applications are available as standalone, no-install software packages.
• espeak-ng: This is a key dependency for text-to-speech conversion and should be installed to work out-of-the-box.

Users will need to download and run these separate components, with ChatGPT configured to enable voice features via the LangHelper interface. For an AI-driven voice interaction, which requires PyTorch libraries, users must integrate the LangHelper with the ChatGPT desktop edition appropriately.

Usage Tips

• Setting Up and Configuration: After downloading, extract the components into desired folders, run LangHelper, and await ChatGPT's startup. Configuration occurs in ChatGPT’s Preferences under Control Center, aligning with the speech settings before submission and restarting.

• Testing Voice Features: Use the trial text function within settings to ensure AI voices are functioning properly before starting real conversations. This process helps diagnose and fix potential issues in the setup.

• Speech Recognition: Activate recognition through the designated toggle within the interface; remember to disable it after completing interactions to preserve system resources.

IELTS Prompt Customization

For users wanting to simulate an IELTS speaking test scenario, LangHelper allows custom prompt creation. Users can generate prompts for a realistic practice environment, providing spoken text and pronunciation scores iteratively through the software's speech recognition and assessment technologies.

Project Mission

LangHelper’s mission is to democratize language learning, making interactive, speech-based learning tools accessible to everyone, including non-PLUS users of ChatGPT. It aims to continually expand its feature set, catering to various accents and speech recognition capabilities, to support the world in breaking down language barriers.

LangHelper is a promising tool for enhancing language proficiency, providing an engaging, interactive platform that fosters speaking and listening skills through cutting-edge AI technology.
