Hello Developers!
Welcome to the eleventh session of our series “How to Become Flutter Developer with AI integration”.
I am Lavi Sengar, Flutter Developer and Tutor at Dectac, and in this session, we give your Flutter apps a voice. After making your apps “think” (text generation) and “see” (image generation), this week we’ll explore how to make them listen and understand speech using speech-to-text technology.
We’ll cover both on-device speech recognition (using Flutter’s speech_to_text plugin) and AI-powered cloud transcription (using OpenAI’s Whisper API). Whether you're a complete beginner or want to learn something new and advanced, this video is for you.

Why Learn Voice Input?
Voice is the future of human-computer interaction. It improves accessibility, adds hands-free convenience, and opens doors to apps like voice assistants, dictation tools, and language learning platforms.
