  "raw_analysis": "IMPORTANT: This service was incorrectly routed to platform analysis. IBM Text to Speech is a full-featured REST API service, not a platform without an API. It's part of IBM Watson's AI services suite and provides comprehensive text-to-speech conversion capabilities through well-documented REST endpoints. The service supports multiple languages, voice options, SSML markup, custom voice models, and pronunciation dictionaries. It uses IBM Cloud IAM authentication and offers both free tier and usage-based pricing. This should be analyzed by the API analyzer, not the platform analyzer, as it has extensive REST API functionality with proper authentication, rate limiting, and enterprise-grade features."
