# Proposal: Add Voice Communication System
|
|
|
|
**Change ID:** `add-voice-communication`
|
|
**Status:** Proposed
|
|
**Type:** Feature
|
|
**Priority:** Critical (MVP)
|
|
**Target Release:** v0.1.0
|
|
|
|
## Summary
|
|
|
|
Implement the core voice communication system for OpenSpeak, enabling real-time voice transmission between clients through the server. This includes audio capture, Opus encoding, packet routing, and playback functionality.
|
|
|
|
## Problem Statement
|
|
|
|
OpenSpeak requires a real-time voice communication system where:
|
|
- Users can capture audio from microphones and transmit to server
|
|
- Server routes voice packets to all members in a channel
|
|
- Users receive and play back multiple concurrent voice streams
|
|
- Latency is minimized (<100ms round-trip)
|
|
- Audio quality is maintained while optimizing bandwidth
|
|
|
|
## Solution Overview
|
|
|
|
Implement a voice streaming system using:
|
|
- **Opus codec** for encoding/decoding at 64kbps (8-128kbps configurable)
|
|
- **gRPC bidirectional streaming** for real-time packet transport
|
|
- **Server broadcast model** where server receives packets and broadcasts to channel
|
|
- **Client-side audio mixing** for multiple speakers
|
|
- **Jitter buffer** for handling packet timing variations
|
|
|
|
## Impact
|
|
|
|
### Affected Capabilities
|
|
- New: Voice Communication
|
|
- New: Audio Streaming
|
|
- New: Voice Routing
|
|
- Depends on: Channel Management, Authentication, Presence Tracking
|
|
|
|
### Users/Stakeholders
|
|
- End users: Can speak and hear in voice channels
|
|
- Developers: Must implement audio subsystem
|
|
- DevOps: Must support audio packet forwarding
|
|
|
|
## Success Criteria
|
|
|
|
- [ ] Voice packets route correctly from source to channel members
|
|
- [ ] Audio latency is <100ms round-trip in typical network conditions
|
|
- [ ] Supports 10+ concurrent speakers in single channel
|
|
- [ ] Opus encoding/decoding works with <5% CPU per stream
|
|
- [ ] Handles packet loss up to 2% without noticeable degradation
|
|
- [ ] Unit test coverage >80% for voice subsystem
|
|
- [ ] Integration tests pass for client-server voice communication
|
|
|
|
## Implementation Phases
|
|
|
|
### Phase 1: Core Voice Routing (Week 1-2)
|
|
- [ ] Define VoicePacket protobuf message
|
|
- [ ] Implement server voice router component
|
|
- [ ] Implement client voice capture and encoding
|
|
- [ ] Implement client voice reception and decoding
|
|
|
|
### Phase 2: Audio Quality (Week 2-3)
|
|
- [ ] Implement jitter buffer for timing
|
|
- [ ] Add packet loss handling
|
|
- [ ] Tune Opus bitrate settings
|
|
- [ ] Add volume normalization
|
|
|
|
### Phase 3: Integration & Testing (Week 3-4)
|
|
- [ ] Integration tests for voice communication
|
|
- [ ] Performance benchmarks
|
|
- [ ] Stress tests with many speakers
|
|
- [ ] Documentation and examples
|
|
|
|
## Risks & Mitigations
|
|
|
|
| Risk | Probability | Impact | Mitigation |
|
|
|------|-------------|--------|-----------|
|
|
| Audio library compatibility issues | Medium | High | Test with PortAudio, have fallback plan |
|
|
| Network latency exceeds target | Low | Medium | Implement jitter buffer, tune codec settings |
|
|
| Memory usage with many streams | Low | Medium | Implement stream pooling, monitor memory |
|
|
| CPU usage too high | Low | High | Profile early, optimize hot paths |
|
|
|
|
## Open Questions
|
|
|
|
1. Should we use PortAudio or OS-specific audio APIs?
|
|
2. What's the minimum jitter buffer size?
|
|
3. Should we implement echo cancellation?
|
|
4. Should voice activity detection be enabled by default?
|
|
|
|
