3. Introduction
 A voice assistant is a technology based on artificial intelligence. The
software uses a device’s microphone to receive voice requests while the
voice output takes place at the speaker. But the most exciting thing
happens between these two actions.
 It is a combination of several different technologies: voice recognition,
voice analysis and language processing.
 It is completely developed using one of the most powerful language
python.

Problem Statement
 The main aim of our project is that we have created a function, Intelligent Personal Assistant
which can perform mental tasks like turning on/off smart phone applications with the help of
Voice User interface (VUI) which is used to listen and process audio commands.
Scope
 The voice assistant application market is projected to grow at 27.3% CAGR during the forecast
period of 2021-2026.
 A voice assistant is primarily a digital assistant built upon using AI, machine learning, and voice
recognition technologies.
Objective
1.The project aims to help visually impaired individuals access important phone features.
2. To introduce advanced voice assistant systems for individuals with vision impairment
3. To guide visually impaired individuals in performing day-to-day tasks.

9. MODELS
 ACOUSTIC MODELS
• Acoustic model is a relationship between audio signal and phoneme
• Phoneme means one of the smallest unit of speech that make one word different from another
word
 PRONUNCIATION DICTIONARY
• The act or result of producing the sounds of speech, including articulation, stress, and intonation
• A phonetic transcription of a given word, sound, etc.
• An accepted standard of the sound and stress patterns of a word, phrase, etc.
 LANGUAGE MODELS
• The language model provides context to distinguish between words and phrases that sound
similar.
for example, In American English the phrases “recognize speach” and “wreck a
nice beach” sound similar , but mean different things.

18. Conclusion
Voice Controlled Assistant System will use the Natural language
processing and can be integrated with artificial intelligence techniques
to achieve a smart assistant that can control the computer and
applications and even solve user queries using web searches.. It can be
designed to minimize the human efforts to interact with many other
subsystems, which would otherwise have to be performed manually. By
achieving this, the system will make human life comfortable
