What is NewsVoice?

Imagine catching up on the latest news during your morning commute without having to read through lengthy articles or struggle with language barriers. NewsVoice was born out of the desire to make news more accessible, especially for Punjabi-speaking audiences who prefer consuming content in their native language. The application bridges several gaps:

• Time Constraints: Provides concise summaries, saving users time.
• Language Accessibility: Translates content into Punjabi for native speakers.
• Ease of Consumption: Converts text to speech, allowing for hands-free listening.

Whether you’re a busy professional, a commuter, or someone with visual impairments, NewsVoiceAI offers a seamless way to stay informed.

Key Features of NewsVoice

• Live News Fetching: Pulls the latest news articles from reputable sources like The Guardian using their API.
• AI-Powered Summarization: Utilizes advanced AI models from OpenAI to condense lengthy articles into brief summaries.
• Punjabi Translation: Ensures regional accessibility by accurately translating summaries into Punjabi.
• Text-to-Speech Conversion: Generates clear and natural-sounding Punjabi audio using state-of-the-art TTS technologies.
• User-Friendly Interface: Built with Streamlit, offering an interactive and intuitive user experience.

How NewsVoice Works?

Let’s explore the step-by-step workflow of NewsVoice, integrating code snippets to illustrate each part.

Step1: Fetch News Articles

Using The Guardian API, NewsVoiceAI retrieves the top live news articles based on predefined criteria or user preferences.

Implementation

# Function to fetch news articles from The Guardian API
def fetch_news(api_key):
    from theguardian import theguardian_content
    content = theguardian_content.Content(api=api_key)
    json_content = content.get_content_response()
    try:
        return content.get_results(json_content)
    except KeyError as e:
        st.error(f"Error fetching articles: {e}")
        return []

Explanation:

• We use the theguardian library to interact with The Guardian API.
• The fetch_news function retrieves articles and handles any potential errors.

Step2: Fetch Article Content

For each article, we fetch the full content to prepare it for summarization.

Implementation

# Function to fetch article content
def fetch_article_content(article_url, api_key):
    response = requests.get(article_url, params={"api-key": api_key, "show-blocks": "all"})
    if response.status_code == 200:
        article_data = response.json()
        body = article_data.get("response", {}).get("content", {}).get("blocks", {}).get("body", [])
        if body:
            return " ".join(block.get("bodyTextSummary", "") for block in body)
    return None

Explanation:

• The function sends a GET request to the article’s API URL with parameters to retrieve the full content.
• It parses the JSON response to extract the text of the article.

Step3: Summarize and Translate Content Using OpenAI API

We use OpenAI’s GPT models to summarize the article and then translate the summary into Punjabi.

Implementation

# Function to summarize and translate content using OpenAI API
def summarize_and_translate(content, api_key):
    import openai
    openai.api_key = api_key
    
    # Summarization Prompt
    summary_response = openai.ChatCompletion.create(
        model="gpt-4", 
        messages=[
            {"role": "system", "content": "You are a helpful assistant that summarizes news articles concisely."},
            {"role": "user", "content": f"Summarize the following article content in 2-3 sentences:\n\n{content}"}
        ],
        max_tokens=100
    )
    summary = summary_response.choices[0].message.content.strip()
    
    # Translation Prompt
    translation_response = openai.ChatCompletion.create(
        model="gpt-3.5-turbo",
        messages=[
            {"role": "system", "content": "You are a professional translator specializing in English to Punjabi translations."},
            {"role": "user", "content": f"Translate the following text to Punjabi:\n\n{summary}"}
        ],
        max_tokens=150
    )
    translation = translation_response.choices[0].message.content.strip()
    
    return summary, translation

Explanation:

• We initialize the OpenAI API with the provided key.
• The summarize_and_translate function first summarizes the article content.
• It then translates the summary into Punjabi.
• Both operations use the ChatCompletion endpoint with appropriate prompts.

Step4: Convert Punjabi Text to Speech Using Sarvam TTS API

The translated text is converted into audio using the Sarvam TTS API.

Implementation

# Function to convert Punjabi text to speech using Sarvam TTS API
def punjabi_text_to_speech(punjabi_text, sarvam_api_key):
    url = "https://api.sarvam.ai/text-to-speech"
    
    # Split text into chunks of up to 500 characters
    chunks = [punjabi_text[i:i 500] for i in range(0, len(punjabi_text), 500)]
    audio_clips = []
    
    for i, chunk in enumerate(chunks):
        payload = {
            "inputs": [chunk],
            "target_language_code": "pa-IN",
            "speaker": "meera",
            "pitch": 0,
            "pace": 1.0,
            "loudness": 1.2,
            "speech_sample_rate": 8000,
            "enable_preprocessing": True,
            "model": "bulbul:v1"
        }
        headers = {
            "Content-Type": "application/json",
            "API-Subscription-Key": sarvam_api_key
        }
    
        response = requests.post(url, headers=headers, json=payload)
    
        if response.status_code == 200:
            audio_base64 = response.json().get("audios")
            if audio_base64 and len(audio_base64) > 0:
                audio_clips.append(audio_base64[0])
            else:
                st.error(f"No audio found in response for chunk {i 1}.")
                return None
        else:
            st.error(f"Failed to convert chunk {i 1} to speech: {response.status_code} - {response.text}")
            return None
    
    # Combine all Base64 audio chunks into a single string
    return "".join(audio_clips)

Explanation:

• The function handles the API’s character limit by splitting the text into chunks.
• It sends each chunk to the TTS API and collects the Base64-encoded audio.
• The audio chunks are concatenated to form the complete audio file.

Step5: Build the Streamlit Interface

The user interface is built using Streamlit, providing an interactive experience.

Implementation

# Main Streamlit App
def main():
    st.set_page_config(
        page_title="NewsVoice: Multilingual News Summaries",
        page_icon="?",

            if not articles:
                st.warning("No articles found. Please try again.")
            else:
                # Process top selected number of articles
                for article in articles[:num_articles]:
                    english_title = article.get('webTitle', 'No title available')

                        # Fetch article content
                        article_content = fetch_article_content(article_url, GUARDIAN_API_KEY) if article_url else None
                        
                        if not article_content:
                            st.write("No content available for this article.")
                            continue
    
                        try:
                            # Summarize and Translate
                            summary, punjabi_translation = summarize_and_translate(article_content, OPENAI_API_KEY)
                            
                            # Display English Summary
                            st.markdown("**English Summary:**")

                            audio_base64 = punjabi_text_to_speech(punjabi_translation, SARVAM_API_KEY)
    
                            if audio_base64:
                                audio_bytes = base64.b64decode(audio_base64)
