Text to Speech Generator

Purpose & User Intent: This tool provides an online interface to convert text into speech using Microsoft TTS voices. It targets developers integrating TTS into apps, content teams producing narrated media, localization specialists generating multilingual audio, and accessibility professionals creating audio alternatives. Common use cases include UI prompts, tutorials, onboarding content, and narrated content for videos or e-learning. Assumption: the keyword implies an online interface that leverages Microsoft TTS via an API and outputs audio files for integration. When to use: for automating voice asset creation, quick prototyping of voice personas, and scalable audio generation for multilingual projects.

Core Logic & Features: Domain capabilities include text validation, voice catalog access, parameter mapping for rate, pitch, and volume, SSML interpretation, and multi-format audio export. Required features: text input, voice selection, output format, and synthesis trigger. Optional/advanced features: rate, pitch, volume, language locale, SSML control, batch processing, consistent naming, API key management, and basic error retries.

Inputs & Outputs: Inputs include text (string, required), voice (string, required), rate (float, optional, range -50 to 50%), pitch (float, optional, -20 to 20%), volume (float, optional, 0 to 1), format (string, mp3/wav/ogg, required), locale (string, optional). Outputs include audio_file (URL/blob), duration_seconds (float), sample_rate (int), encoding (string), file_size (int), and quality metadata.

Algorithms & Calculations: The tool delegates synthesis to the Microsoft TTS service, forwarding SSML when provided and applying voice/selective parameter mappings. Duration estimates come from API metadata; results can be cached for performance; error handling uses retries and fallbacks where supported.

Error & Edge Cases: Invalid or overly long text, unsupported voice or locale, rate/pitch out of range, API downtime, network failures, and quota limits. Large texts may require chunking; unsupported combinations should return a precise error code without UI messaging.

Industry/Region & Localization: Defaults to en-US voice catalog with locale-aware processing where Microsoft TTS supports it; follows standard API regional compliance and data handling practices. Assumptions & Exclusions: Assumes online, API-based access to Microsoft TTS and does not cover offline synthesis, non-MS voices, or non-text inputs; data handling is scoped to processing session and API terms.
