1. What is the primary advantage of realtime voice APIs like OpenAI Realtime compared to voice assistants that convert speech to text first?

   1. They can process audio directly without intermediate text conversion, reducing delay
   2. They use less battery power on mobile devices
   3. They require less internet bandwidth than traditional voice assistants
   4. They can store conversations for later playback

2. What does the lesson identify as a current limitation of realtime voice APIs in multi-speaker conversations?

   1. They struggle with single speakers but excel with groups
   2. They cannot reliably handle complex multi-speaker calls
   3. They work perfectly with multiple speakers but not solo users
   4. They can identify each speaker by name automatically

3. Why does the lesson compare voice data to biometric data?

   1. Voice carries identity, emotion, and location cues that require careful handling
   2. Voice APIs require fingerprint scanners to function
   3. Biometric data is faster to process than audio data
   4. Voice data is less secure than text data from AI systems

4. What latency target do realtime voice APIs aim to achieve for natural conversations?

   1. Under 2 seconds
   2. Under 100 milliseconds
   3. Under 10 seconds
   4. Under 500 milliseconds

5. Which capability is described as enabling 'natural' conversation flow in realtime voice APIs?

   1. The ability to interrupt and be interrupted naturally
   2. The ability to pause and resume without context loss
   3. The ability to speak without any pauses
   4. The ability to automatically lower volume during speech

6. In a noisy conference room, what limitation would a user likely experience with a realtime voice API?

   1. The API would automatically filter out all background noise
   2. The API would work perfectly since it processes audio directly
   3. The API would require the user to type instead of speak
   4. The API cannot match human listening accuracy in noisy rooms

7. What is the primary benefit of achieving sub-second latency in voice conversations?

   1. It reduces the cost of API calls
   2. It allows the AI to think longer before responding
   3. It enables fluid, natural-sounding voice conversation
   4. It allows for longer conversations without disconnection

8. A brainstorming partner is listed as an appropriate use case for realtime voice APIs. Why might this be suitable?

   1. Because brainstorming requires formal documentation that voice provides
   2. Because brainstorming must be done with multiple people simultaneously
   3. Because voice APIs can generate written summaries automatically
   4. Because voice conversation allows for free-flowing, natural idea exchange

9. What emotional information can realtime voice APIs potentially detect from a user's voice?

   1. The user's age and height
   2. Only the words being spoken
   3. The user's location within a building
   4. Tone and emotion in the user's voice

10. Why might a contract review process be unsuitable for realtime voice APIs?

    1. Voice APIs are too expensive for business use
    2. Contracts must be reviewed by humans, not AI
    3. Contracts require precise wording and audit trails that voice alone doesn't provide
    4. Voice APIs cannot read documents aloud

11. Which group of users might benefit most from realtime voice APIs for accessibility?

    1. Users who speak only one language
    2. Users with visual impairments who need voice interaction
    3. Users who prefer reading to listening
    4. Users who prefer typing over speaking

12. When a user interrupts a conversation with a realtime voice API, what should theoretically happen?

    1. The API continues talking until finished
    2. The conversation ends immediately
    3. The API requires the user to wait
    4. The API can handle interruption naturally

13. What does the term 'latency' refer to in the context of realtime voice APIs?

    1. The duration of the longest possible conversation
    2. The number of languages the API supports
    3. The volume level of the audio output
    4. The time between user speech and API response

14. Why are realtime voice APIs particularly well-suited for language tutoring?

    1. Because they enable natural conversation practice with immediate feedback
    2. Because they can grade written exams automatically
    3. Because they require no internet connection
    4. Because they translate text between languages

15. What caution does the lesson advise about storing or handling realtime voice data?

    1. Voice data can be freely shared without consent
    2. Voice data should be treated like biometric data due to its sensitivity
    3. Voice data is not personally identifiable
    4. Voice data requires no special security measures
