Speech synthesis, also known as text-to-speech (TTS), is the AI workload that converts written text into spoken words. In this case, the task is to generate narration audio from provided scripts for silent instructional videos.

Speech recognition performs the opposite function — it converts speech into text. Language modeling is for text understanding and prediction (e.g., GPT). Translation converts text between languages, not from text to audio.

Therefore, the most appropriate workload, according to Microsoft’s AI-900 study material under the “Speech AI capabilities” section, is speech synthesis, which enables natural voice narration generation.

According to the Microsoft Azure AI Fundamentals (AI-900) official study guide and Microsoft Learn module “Describe core concepts of machine learning on Azure”, the Azure Machine Learning Designer is a drag-and-drop, no-code/low-code interface that allows users to build, test, and deploy machine learning models visually without needing to write extensive code.

Drag-and-Drop Visual Canvas → YESThe Azure Machine Learning Designer indeed provides a graphical interface where users can connect prebuilt modules for data preprocessing, training, evaluation, and deployment. Microsoft documentation describes it as a “drag-and-drop visual environment that simplifies machine learning model creation.” This allows beginners and business users to construct machine learning pipelines intuitively, confirming this statement as True.

Save Progress as a Pipeline Draft → YESThe designer lets users save their current work as a pipeline draft, enabling them to pause and return later. Microsoft Learn explicitly states that you can “save and publish pipeline drafts before running or deploying them.” This functionality ensures workflow continuity, collaboration, and version management—making this statement also True.

Include Custom JavaScript Functions → NOThe Azure Machine Learning Designer allows the integration of Python scripts through the “Execute Python Script” module for custom logic, but it does not support JavaScript. Custom code in the designer environment is limited to Python, as the platform is built for data science and machine learning tasks typically handled in Python-based environments. Therefore, this statement is False.

The Translator Text service (part of Azure Cognitive Services) provides real-time text translation across multiple languages. According to Microsoft Learn’s AI-900 module on “Identify features of Natural Language Processing (NLP) workloads”, translation is one of the four main NLP tasks, alongside key phrase extraction, sentiment analysis, and language understanding.

In this scenario, the company wants to make press releases available in a range of languages, which requires converting text from one language to another while preserving meaning and tone. The Translator Text API supports more than 100 languages and can be integrated into web apps, chatbots, or content management systems for automatic multilingual publishing.

The other options perform different functions:

Text Analytics (B) extracts insights such as key phrases or sentiment but does not translate.

Speech (C) focuses on converting between speech and text, not text translation.

Language Understanding (LUIS) (D) identifies user intent but does not perform translation.

Therefore, to provide multilingual press releases, the appropriate service is A. Translator Text, which ensures accurate, fast, and scalable translation across global audiences.
