Enhance PhoneBlock-AB with Local AI for Intelligent Scam Call Conversations #187

@SchulteDev

Description

@SchulteDev

Summary

Replace AB pre-recorded responses with real-time AI conversations engage spam callers for a longer period.

Inspired by (O2) AI Scam Adviser – Meet dAIsy, the scam-fighting AI bot

Current Limitations

  • Voice Activity Detection (silence/speech detection)
  • Fixed pre-recorded WAV responses
  • No conversation understanding or context awareness
  • Predictable patterns easily recognized by experienced telemarketers

Proposed Java-Native Solution

I think that a purely local implementation makes sense from a cost perspective and for data protection reasons.

  1. Speech-to-Text: whisper-jni
  2. Dialog AI: llama.cpp Java bindings
  3. Text-to-Speech: Piper TTS via JNI or existing Java TTS
