Integration with other Azure services provides end-to-end solutions. Transcribed text can be sent to Text Analytics for sentiment analysis or entity extraction, stored in Azure SQL Database or Cosmos DB for reporting, and visualized in Power BI dashboards. Speech to Text can also be combined with Translator to support real-time translation of audio streams, enabling multinational organizations to communicate across languages seamlessly.
Unlike Computer Vision, which interprets images or video, or Text Analytics, which analyzes textual content, Speech to Text focuses on converting audio signals into machine-readable text. The service provides options to handle different formats, noise reduction, speaker diarization, and punctuation insertion, making the transcribed content highly usable for downstream processing.
Security is a critical aspect. Azure ensures all audio data is encrypted in transit and at rest. Access control can be enforced via Azure Active Directory, and users can manage resource usage and monitor service health. Compliance with GDPR, HIPAA, and other standards ensures that sensitive voice data is handled responsibly. AI-900 candidates should understand the functionality of Speech to Text, its integration scenarios, supported languages and formats, and the real-world applications for automated transcription and accessibility, as these are common exam topics and practical use cases in enterprise AI deployments.
Question 75:
Which Azure AI service can provide image analysis for object detection, scene recognition, and optical character recognition (OCR)
Answer:
A) Azure Cognitive Services – Computer Vision
B) Azure Cognitive Services – Form Recognizer
C) Azure Cognitive Services – Text Analytics
D) Azure Bot Service
Correct Answer A)
Explanation:
Azure Cognitive Services – Computer Vision is an AI service designed to analyze visual content in images and videos. It provides object detection, scene recognition, optical character recognition (OCR), image classification, and spatial analysis, enabling applications to interpret visual data and extract actionable insights. Organizations across industries such as retail, manufacturing, healthcare, and security leverage Computer Vision to automate tasks that traditionally required human visual inspection, reducing errors, speeding up processing, and enhancing efficiency.
Object detection allows the service to identify and locate specific objects within an image. For instance, a retail store can use object detection to track inventory on shelves, monitor product placement, or identify misplaced items. Scene recognition enables understanding the broader context of an image, such as indoor versus outdoor environments or specific activities being performed. OCR extracts text from images, including scanned documents, signage, or labels, converting them into machine-readable text that can be indexed, stored, or further analyzed.
Integration with other Azure services enhances its usefulness. Extracted data can be sent to Azure Cognitive Search for content indexing, to Power BI for visualization, or combined with Form Recognizer for documents containing both text and structural elements. Unlike Text Analytics, which focuses on textual data, or Bot Service, which manages conversational AI, Computer Vision deals with visual inputs and converts them into structured insights.
The service supports advanced features such as handwriting recognition, spatial analysis, and custom vision models. Custom Vision allows training of domain-specific image classifiers for specialized applications, such as detecting defects on production lines or recognizing specific logos. Security and compliance are maintained through encrypted data storage, secure API access, and adherence to industry regulations, ensuring sensitive visual information is handled appropriately.
Candidates preparing for AI-900 should understand Computer Vision capabilities, supported tasks, integration scenarios, and practical applications for automation and insight generation from visual data. Knowledge of how it differs from other cognitive services, its real-world impact, and security considerations is essential for both exam success and practical implementation of AI solutions in the Azure ecosystem.
