From 9da150df8b0fc7e95dbd554d5c39a6bfb29de067 Mon Sep 17 00:00:00 2001 From: manavgup Date: Mon, 13 Oct 2025 12:57:42 -0400 Subject: [PATCH 1/8] feat: Add database models and schemas for custom voice upload feature (#394) This commit implements the foundational infrastructure for custom voice support: **Database Model** (backend/rag_solution/models/voice.py): - Voice model with fields for name, description, gender, status - Support for provider integration (provider_voice_id, provider_name) - Voice sample storage tracking (file URL, size, quality score) - Usage tracking and error handling - Timestamps for creation, update, and processing completion **Pydantic Schemas** (backend/rag_solution/schemas/voice_schema.py): - VoiceUploadInput - Voice upload with metadata - VoiceOutput - Voice information response - VoiceListResponse - List user's voices - VoiceProcessingInput - Process voice with TTS provider - VoiceUpdateInput - Update voice metadata - Validation for name, gender, and supported providers **Model Integration**: - Updated User model to include voices relationship - Registered Voice model in models/__init__.py **Documentation** (CUSTOM_VOICE_IMPLEMENTATION_PROGRESS.md): - Complete implementation plan - Architecture decisions - Remaining tasks breakdown - API usage examples - Configuration requirements Remaining work: - Voice storage system - Voice repository and service - Voice API endpoints - ElevenLabs provider integration - Podcast generation integration - Tests and migration Related to #394 ---

This consolidates all file operations in one place. **FileManagementService Updates** (backend/rag_solution/services/file_management_service.py): - Added save_voice_file() - Upload voice samples with format validation - Added get_voice_file_path() - Get voice sample path (searches all formats) - Added delete_voice_file() - Delete voice samples with directory cleanup - Added voice_file_exists() - Check voice sample existence **Voice Storage Structure**: - Path: {storage_path}/{user_id}/voices/{voice_id}/sample.{format} - Supported formats: mp3, wav, m4a, flac, ogg - Automatic directory cleanup on deletion **Voice Repository** (backend/rag_solution/repository/voice_repository.py): - Complete CRUD operations for Voice model - Status management with provider integration - Usage tracking (increment_usage) - Schema conversion (to_schema) - Transaction management and error handling **Benefits**: - Single service for all file operations (documents, voices, podcasts) - Simpler architecture with less code duplication - Easier to maintain and test - Existing methods unchanged (backward compatible) Related to #394 --- .../repository/voice_repository.py | 369 ++++++++++++++++++

Values (Code) + +**Location:** `backend/rag_solution/schemas/llm_parameters_schema.py` + +```python +class LLMParametersInput(LLMParametersBase): + max_new_tokens: int = Field( + default=100, # Conservative default + ge=1, # Minimum (must generate something) + # NO upper limit - model-dependent + description="Maximum tokens (WatsonX ~2K, GPT-4 ~128K, Claude ~200K)" + ) +``` + +**Design Rationale:** +- **No `le` (upper limit)**: Different models have vastly different capabilities +- **Low default (100)**: Safe for general Q&A, fast responses +- **Descriptive**: Documents model-specific limits + +### User Configuration (Database) + +**Location:** `llm_parameters` table + +**Access Methods:** +1. **REST API:** `/api/users/{user_id}/llm-parameters` +2. **UI:** Settings page (to be implemented) +3. **CLI:** `rag-cli config llm-params set` + +**User Benefits:** +- Persist preferences across sessions +- Different configs for different tasks +- Team-wide or personal settings + +### Service Overrides (Runtime) + +**Location:** Service-specific logic (e.g., `podcast_service.py`) + +```python +# Override for long-form content +podcast_params = LLMParametersInput( + user_id=user_id, + max_new_tokens=max_word_count * 3, # Context-specific calculation + temperature=0.7, + # ... other params +) + +llm_provider.generate_text(model_parameters=podcast_params) +``` + +**When to Use Service Overrides:** +- Task requires significantly different parameters +- Safety-critical operations (lower temperature) +- Long-form content (higher token limits) +- Batch processing (higher batch sizes) + +## Best Practices + +### 1. **Progressive Disclosure** + +``` +Basic UI: [Temperature] [Max Tokens] + โ†“ "Show Advanced" +Advanced: [Top-K] [Top-P] [Repetition Penalty] [Batch Size] [etc.] +``` + +**Rationale:** Most users only need 2-3 parameters, advanced users get full control. + +### 2. **Validation at Multiple Levels** + +```python +# Schema-level: Basic constraints +max_new_tokens: int = Field(ge=1, description="...") + +# Service-level: Business logic +if task == "podcast" and max_new_tokens < 1000: + logger.warning("Podcast may be truncated with %d tokens",

max_new_tokens = 2048 +``` + +### 3. **Document Model Capabilities** + +**Maintain a model registry:** + +```python +MODEL_CAPABILITIES = { + "ibm/granite-3-8b-instruct": { + "max_tokens": 2048, + "context_window": 8192, + "supports_streaming": True, + }, + "gpt-4-turbo": { + "max_tokens": 4096, + "context_window": 128000, + "supports_streaming": True, + }, + "claude-3-opus": { + "max_tokens":

capability +- Smart defaults: Suggest optimal parameters per model + +### 4. **Presets for Common Tasks** + +```python +PARAMETER_PRESETS = { + "qa_short": { + "max_new_tokens": 100, + "temperature":

This feature provides per-turn TTS provider selection, custom voice resolution, and intelligent audio stitching. + +## Key Features + +### 1. Per-Turn Provider Selection + +Each dialogue turn can use a different TTS provider based on the voice selected: + +```python +# Example: HOST using custom ElevenLabs voice, EXPERT using OpenAI voice +{ + "host_voice": "38c79b5a-204c-427c-b794-6c3a9e3db956", // Custom voice (UUID) + "expert_voice": "nova" // OpenAI predefined voice +} +``` + +The system automatically: +- Detects voice ID format (UUID = custom, string = predefined) +- Resolves custom voices from database +- Selects appropriate TTS provider per turn +- Generates audio segments +- Stitches segments together with natural pauses + +### 2. Custom Voice Resolution + +**UUID-Based Detection**: +```python +async def _resolve_voice_id(self, voice_id: str, user_id: UUID4) -> tuple[str, str | None]: + """ + Resolve voice ID to provider-specific voice ID. + + UUID format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx + Returns: (provider_voice_id, provider_name) + """ +``` + +**Validation Steps**: +1. Parse voice ID as UUID +2. Look up custom voice in database +3. Validate ownership (user_id matches) +4. Check voice status (must be "ready") +5. Return provider-specific voice ID and provider name + +### 3. Supported Providers + +| Provider | Voice Types | Use Cases | +|----------|------------|-----------| +| **OpenAI TTS** | Predefined voices (alloy, echo, fable, onyx, nova, shimmer) | Quick generation, consistent quality | +| **ElevenLabs** | Custom cloned voices + presets | Brand voices, personalized podcasts | +| **WatsonX TTS** | IBM Watson voices | Enterprise deployments | + +### 4. Audio Stitching + +**Technical Implementation**: +```python +# Generate audio for each turn with appropriate provider +for turn in script.turns: + voice_id = host_voice_id if turn.speaker == Speaker.HOST else expert_voice_id + provider = get_provider(provider_type) + segment = await provider._generate_turn_audio(...) + audio_segments.append(segment) + + # Add 500ms pause between turns + if idx < len(script.turns) - 1: + pause = AudioSegment.silent(duration=500) + audio_segments.append(pause) + +# Combine all segments +combined = AudioSegment.empty() +for segment in audio_segments: + combined += segment +``` + +**Benefits**: +- Seamless transitions between providers +- Natural pauses between speakers +- Single output file (MP3, WAV, OGG, FLAC) + +## Configuration + +### Environment Variables + +Add to your `.env` file: + +```bash +# Default audio provider for podcasts +PODCAST_AUDIO_PROVIDER=openai # Options: openai, elevenlabs, watsonx + +# OpenAI TTS Configuration +OPENAI_API_KEY=your-openai-api-key +OPENAI_TTS_MODEL=tts-1-hd +OPENAI_TTS_DEFAULT_VOICE=alloy + +# ElevenLabs TTS Configuration +ELEVENLABS_API_KEY=your-elevenlabs-api-key +ELEVENLABS_API_BASE_URL=https://api.elevenlabs.io/v1 +ELEVENLABS_MODEL_ID=eleven_multilingual_v2 +ELEVENLABS_VOICE_SETTINGS_STABILITY=0.5 +ELEVENLABS_VOICE_SETTINGS_SIMILARITY=0.75 +ELEVENLABS_REQUEST_TIMEOUT_SECONDS=30 +ELEVENLABS_MAX_RETRIES=3 +``` + +Get your API keys: +- **OpenAI**: [https://platform.openai.com/api-keys](https://platform.openai.com/api-keys) +- **ElevenLabs**: [https://elevenlabs.io/app/settings/api-keys](https://elevenlabs.io/app/settings/api-keys) + +### Provider Configuration + +The system uses `AudioProviderFactory` to create provider instances: + +```python +from rag_solution.generation.audio.factory import AudioProviderFactory + +# Create provider from settings +provider = AudioProviderFactory.create_provider( + provider_type="elevenlabs", # or "openai", "watsonx" + settings=settings +) + +# List available providers +providers = AudioProviderFactory.list_providers() +# Returns: ["openai", "elevenlabs", "watsonx", "ollama"] +``` + +## Usage + +### 1.
