Custom Text-to-Speech Python Script/App

TITLE: Need a Python Script or Android App for Text-to-Speech (Fixed Budget: ₹1,000 INR)

DESCRIPTION:
Hi, I need a personal Text-to-Speech (TTS) tool (either a simple Android app or a Python script) for my personal use.

Requirements:
1. Budget: Strictly Fixed ₹1,000 INR Maximum. Do not bid if you want more money.
2. File Support: Must support large text files (1MB to 2MB) without crashing or freezing.
3. Voice Quality: Need high-quality, natural-sounding Indian voices (Hindi/English) similar to Pocket FM or professional audiobooks.
4. No Monthly/API Cost: I will NOT pay for Google Cloud, OpenAI, or Azure premium APIs after the app is built. You must use free, unlimited alternatives like the Microsoft Edge-TTS library (using Indian voices like Madhur/Swara) or any other free method with zero maintenance costs.
5. Output: Fast export directly to MP3 files.

Please apply only if you can deliver this exact setup within ₹1,000 INR with zero future costs. Please share a sample demo of the voice quality in chat. Thank you!
