Module 3 Graded Quiz: Create a Voice Assistant

Graded Assignment

1. What is the primary function of IBM Watson Speech-to-Text (STT)?

  • Converts spoken language into written text ✅
  • Provides real-time translation between languages
  • Converts text into spoken language
  • Enhances the emotional intelligence of speech

Explanation:
IBM Watson STT is designed to transcribe audio input into written text in real time or from recordings. It’s widely used for voice commands, transcriptions, and accessibility features.

2. Which feature is not offered by IBM Watson Text-to-Speech (TTS)?

  • Emotion and expressiveness control
  • Real-time speech recognition ✅
  • Expressive and natural voices
  • Customization of voices

Explanation:
Real-time speech recognition is a feature of Speech-to-Text (STT), not TTS. Watson TTS provides natural-sounding voices, customization, and emotion control, but does not recognize speech—it generates speech from text.

3. What is a crucial step in integrating IBM Watson’s speech services into AI projects?

  • Using only default settings for quick setup
  • Obtaining API keys for authentication ✅
  • Memorizing all the API keys manually
  • Avoiding SDKs for more complex integration

Explanation:
To access IBM Watson’s cloud-based services, API keys are essential. They authenticate requests to ensure secure and authorized use of the services.

4. Which of the following is a true statement about integrating IBM Watson Speech Libraries for Embed in AI projects?

  • IBM Watson Speech Libraries are not designed for hybrid multi-cloud environments.
  • IBM Watson Speech Libraries only support the English language for voice transcription and synthesis.
  • IBM Watson Speech Libraries do not support speech-to-text functionality.
  • IBM Watson Speech Libraries offer containerized text-to-speech and speech-to-text libraries for flexibility. ✅

Explanation:
IBM offers containerized libraries that can be deployed in hybrid multi-cloud environments. These allow developers to integrate Watson capabilities into applications with more flexibility and control.

5. What does the process of prompt engineering with GPT-3 enable in voice assistant development?

  • Enables the creation of an assistant that cannot generate original stories
  • Limits the assistant’s ability to understand natural language
  • Reduces the accuracy of voice recognition
  • Allows customization of the voice assistant for various specific purposes through carefully designed inputs ✅

Explanation:
Prompt engineering involves crafting specific inputs (prompts) to guide the model’s output. This enables developers to tailor GPT-3’s responses for different tasks like storytelling, summarizing, or Q&A.

6. How does IBM Watson Speech-to-Text's support for customization improve its application in specialized fields?

  • Increasing audio processing speed regardless of the audio’s quality.
  • By enabling the system to operate independently without internet connectivity.
  • By allowing the recognition system to interpret and transcribe domain-specific terminology more accurately. ✅
  • Decreasing the system’s overall costs by reducing required computational resources.

Explanation:
Custom models in Watson STT let developers train the system on industry-specific vocabulary, improving accuracy in fields like healthcare, finance, or legal transcription.

7. What is Docker’s primary use?

  • Enhancing security protocols
  • Developing, shipping, and running applications as containers ✅
  • Managing database systems
  • Creating virtual machines

Explanation:
Docker is a platform for containerization, which allows developers to package applications with all their dependencies into a container. This ensures consistent behavior across environments—development, testing, and production.
