# Azure AI Services

## Services

| Service | Use When | MCP Tools | CLI |
|---------|----------|-----------|-----|
| AI Search | Full-text, vector, hybrid search | `azure__search` | `az search` |
| Speech | Speech-to-text, text-to-speech, SDK logs | `azure__speech` | - |
| OpenAI | GPT models, embeddings, DALL-E | - | `az cognitiveservices` |
| Document Intelligence | Form extraction, OCR | - | - |

## MCP Server (Preferred)

When Azure MCP is enabled:

### AI Search
- `azure__search` with command `search_index_list` - List search indexes
- `azure__search` with command `search_index_get` - Get index details
- `azure__search` with command `search_query` - Query search index

### Speech
- `azure__speech` with command `speech_transcribe` - Speech to text
- `azure__speech` with command `speech_synthesize` - Text to speech

**If Azure MCP is not enabled:** In Copilot CLI or Claude Code, ask the user to run `/mcp` and enable Azure MCP; in other hosts, ask the user to enable Azure MCP through the host's MCP configuration.

## AI Search Capabilities

| Feature | Description |
|---------|-------------|
| Full-text search | Linguistic analysis, stemming |
| Vector search | Semantic similarity with embeddings |
| Hybrid search | Combined keyword + vector |
| AI enrichment | Entity extraction, OCR, sentiment |

## Speech Capabilities

| Feature | Description |
|---------|-------------|
| Speech-to-text | Real-time and batch transcription |
| Text-to-speech | Neural voices, SSML support |
| Speaker diarization | Identify who spoke when |
| Custom models | Domain-specific vocabulary |
| Client SDK diagnostics | [Speech SDK client diagnostics](references/speech/diagnostics.md) for log collection, offline analysis, features, and session/result IDs (no MCP or login required) |
