Project description:
"I run a marketing-centric calling operation and need an Android app that converts my voice from male to convincingly female in real time during outbound calls. The goal is simple: as I speak, the person on the other end should only hear a natural-sounding woman’s voice, with no noticeable delay or distortion that might raise suspicion or hurt call quality.

Core expectations
• Works on standard Android devices without root, hooking into regular carrier or VoIP calls.
• One-tap toggle before or during a call so I can switch the effect on or off instantly.
• Consistent vocal tone, pitch and cadence that remains stable for an entire conversation, even when I speak loudly, softly or quickly.
• Minimal latency; normal dialogue flow must feel untouched.
• Basic dashboard to adjust pitch range, timbre and background noise suppression.
• Secure storage of any recordings or settings on-device; no external servers unless clearly justified.

I am only targeting Android for this first release, though a clear pathway to iOS later would be a plus if you have the expertise. Please send a detailed project proposal that covers your technical approach (audio libraries, signal processing methods, call interception strategy permitted by Android’s latest policies), timeline and milestones. Demonstrable experience with real-time audio manipulation or telephony APIs will stand out." (client-provided description)
