Murf AI Powered Tour Guide

#murfai #ai #openai #flask

This is a submission for the Murf AI Coding Challenge 2

What I Built

I built Murf Guide Bot - an intelligent, multilingual virtual tour guide that operates through Telegram. This AI-powered travel companion solves the common problem of language barriers and lack of local knowledge that international travelers face.

Key Problem Solved:

  • International tourists often struggle with language barriers when asking for directions or local recommendations
  • Traditional travel apps don't provide voice interaction or multilingual support
  • Tourists need real-time, contextual assistance based on their exact location
  • Many travelers prefer voice interaction over typing, especially when on the move

Solution:
A Telegram bot that combines cutting-edge AI technologies to provide real-time tourism assistance with natural voice interaction in 20+ languages. Users can speak or type their questions and receive both text and audio responses in their preferred language, complete with walking directions and location-based recommendations.

How I Used Murf API

I leveraged Murf AI's APIs in two critical ways to create a seamless multilingual experience:

1. Text-to-Speech (TTS) Service:

  • Integrated Murf's WebSocket TTS API for real-time audio generation
  • Used 20+ different voice IDs to provide natural-sounding speech in multiple languages and accents
  • Implemented streaming audio responses to deliver high-quality voice output instantly
  • Supported languages include English variants, Spanish, French, German, Hindi, Tamil, Chinese, Japanese, Korean, and many more

2. Translation Service:

  • Utilized Murf's translation API to convert responses between languages
  • Enabled seamless language switching based on user preferences
  • Provided real-time translation of tour guide responses to user's preferred language
  • Maintained context and meaning while translating location-specific information

Technical Implementation:

# TTS Integration
async def murf_websocket_tts(text, target_lang):
    voice_id = VOICE_MAP.get(target_lang, "en-US-natalie")
    # WebSocket connection to Murf API for streaming audio
    # Real-time audio generation with natural voice synthesis

# Translation Integration
def translate_text(text: str, target_lang) -> str:
    response = client.text.translate(
        target_language=target_lang,
        texts=[text]
    )
    return response.translations[0].translated_text
