/**
 * Streaming text to speech
 *
 * @remarks
 * Convert text to speech with real-time streaming audio delivery.
 *
 * **Key Features:**
 * - Low-latency audio streaming - playback can start immediately as chunks arrive
 * - Automatic language detection
 * - Multiple format support: MP3 or PCM/WAV
 * - High-quality audio: 24kHz sample rate, 16-bit mono
 *
 * **Request Body:**
 * - `text`: Input text to convert to speech - required
 * - `language`: Language code (default: "auto") - "auto" for automatic detection, or ISO 639-1 codes: en, zh, hi, es, ar, bn, pt, ru, ja, pa, de, ko, fr, tr, it, th, pl, nl, id, vi, ur
 * - `format`: Audio format (default: "mp3") - "mp3" for compressed MPEG audio (96 kbps) or "pcm" for uncompressed WAV
 * - `model`: TTS model identifier (default: "auto") - "auto" selects the default provider; a registry-resolvable id dispatches to the matching provider (note: not all providers support `format: "mp3"`)
 *
 * **Response:**
 * - Streams audio chunks in real-time
 * - Returns `X-Language-Code` header with detected/used language
 * - Content-Type: `audio/mpeg` (MP3) or `audio/wav` (PCM)
 * - When `store` is `true`, returns the `X-Tts-Id` header with the id the history record will be stored under; persistence is best-effort and completes shortly after the stream ends
 *
 * **Use Cases:**
 * - Real-time applications requiring immediate audio playback
 * - Interactive voice responses
 * - Low-latency text-to-speech scenarios
