Android On-Device Speech (TTS & STT) 🎤

Implementing accessible voice interfaces.

⚡ When to Use

• When handling local voice commands or reading text aloud.

🏗️ Core Rules / Pillars

1. Standard TTS initialization

• Pattern: Initialize TextToSpeech and pass OnInitListener. Always wait until initialization is successful before calling .speak().

2. SpeechRecognizer Intent

• Pattern: Use SpeechRecognizer.createSpeechRecognizer(context) and RecognizerIntent.ACTION_RECOGNIZE_SPEECH for local dictation.

🚧 Critical Anti-Hallucination Guards

• Trap: Ensure RECORD_AUDIO permission is requested before initializing the SpeechRecognizer.
