Build me a web browser based Text to Speech App -- 4

YOUR BID PRICE IS FINAL. NO LATER CHANGE ALLOWED. YOU SHOULD HAVE LINUX MACHINE FOR THIS JOB CODING. READ BEFORE BID. I need an experienced programmer who can develop a system of text to speech. I already have a website [login to view URL] for mp3 to text download. It is in Python 3.7 so you should use that. Job Requirements: 1. Install pyttsx3 so that we can choose voice like male, female, change voice speed, volume/pitch, voice emotions like joyful, sad, angry (if possible). Would be best if we could change voice gender, speed in between. 2. Users should be able to upload docx, .srt, .txt or paste inside text box. User can download MP3 after login or email the same after login. Let me know if for .srt file, if you can make a custom code to take time fraction into account. 3. User can also translate uploaded text into English, Spanish, Italian, French, Germán, Portuguese, and Dutch and the voice should be able to speak that language. 4. User should be able to download translated text also. 5. Extend the existing housekeeping as nobody can right-click outside of the text box, extend the feature of auto-deletion of generated MP3 and uploaded files etc. It would be great if it can machine translate the text also before converting it to speech. It should be able to process unlimited words. You should only use an open-source, forever-free library.

I don't pay upfront before bug-free project code delivery on my server SERVER installation to be done by you. I have dockerized, CentOS, 4 GB RAM VPS server. Budget 4k since you don't have to make the site from scratch. Need ND agreement from you
