1. Which two categories form the foundation of audio AI applications?

   1. Transcription and generation
   2. Synthesis and analysis
   3. Classification and summarization
   4. Compression and decompression

2. What type of task is Whisper primarily designed to perform?

   1. Audio noise reduction
   2. Speech-to-text transcription
   3. Voice synthesis and cloning
   4. Text-to-speech generation

3. What is ElevenLabs primarily known for in the audio AI space?

   1. Voice generation and cloning
   2. Real-time speech translation
   3. Audio file compression
   4. Free open-source transcription

4. Before committing to a transcription model, what should be tested on representative audio samples?

   1. Network latency during upload
   2. Cost per minute of audio
   3. Processing speed under ideal conditions
   4. Transcription accuracy with real-world content

5. Even when creating voice clones for parody or entertainment purposes, what requirement must always be met?

   1. A legal waiver must be filed with authorities
   2. The original recording must be publicly available
   3. The voice owner must provide explicit consent
   4. Credit must be given to the original speaker

6. According to the key limitations discussed, can a voice generation model be substituted for a transcription model to achieve high accuracy?

   1. Yes, by fine-tuning on transcription datasets
   2. Yes, if the generation model supports bidirectional processing
   3. No, but only if the audio is in a supported language
   4. No, generation models are not designed for transcription accuracy

7. Why is planning for vendor changes important when selecting audio AI solutions?

   1. To guarantee永远 lowest pricing
   2. To prevent lock-in and ensure flexibility as technology evolves
   3. Vendors always go out of business within one year
   4. Because free tier options expire after six months

8. What is the recommended first step when selecting an audio AI model for a project?

   1. Compare pricing across all available providers
   2. Choose the most popular model on GitHub
   3. Identify the specific use case (transcription vs generation)
   4. Test the fastest model available

9. What should be evaluated when assessing voice generation quality beyond technical accuracy?

   1. The number of languages supported
   2. The file size of generated audio
   3. The year the model was released
   4. The emotional range and naturalness of output

10. When integrating audio AI into an existing application, which factor should be considered?

    1. Compatibility with existing tech stack and workflows
    2. The color scheme of the API dashboard
    3. The physical location of the data center
    4. Whether the model name is trademarked

11. A developer wants to convert podcast episodes into searchable text. Which model category would be appropriate?

    1. Audio compression algorithm
    2. Speech transcription model like Whisper
    3. Voice generation model like ElevenLabs
    4. Video-to-audio converter

12. What ethical consideration is unique to voice generation and cloning technologies compared to transcription?

    1. Language support limitations
    2. Accuracy of transcribed content
    3. Processing speed requirements
    4. Potential misuse for impersonation and deception

13. Why might an organization choose to self-host an audio AI model instead of using an API service?

    1. To avoid paying any costs whatsoever
    2. To automatically receive model updates without action
    3. To keep sensitive audio data within their own infrastructure
    4. To guarantee perfect transcription accuracy

14. What does the lesson recommend regarding testing transcription models before production use?

    1. Use only clean studio-quality audio for testing
    2. Test with pre-recorded demo files only
    3. Skip testing if the model is from a major company
    4. Test on representative audio matching real-world conditions

15. A content creator wants to generate narration for their YouTube videos using AI. Which approach aligns with the lesson's recommendations?

    1. Use a voice generation model like ElevenLabs
    2. Use Whisper to generate the narration audio
    3. Use an audio compression tool for voice generation
    4. Use both Whisper and ElevenLabs interchangeably
