Q61.
Why is synthesized speech often perceived as imperfect?

a.

It lacks natural prosody and intonation

b.

It is transient and cannot be reviewed

c.

It requires the use of headphones

d.

It is intrusive in the office environment

Discuss
Answer: (a).It lacks natural prosody and intonation Explanation:Synthesized speech is often perceived as imperfect because it lacks the natural prosody and intonation present in natural speech, making it difficult for users to adjust to.
Q62.
For which group of users has synthesized speech been particularly successful?

a.

Computer literate individuals

b.

Users with physical disabilities

c.

Individuals with perfect hearing

d.

Novice users

Discuss
Answer: (b).Users with physical disabilities Explanation:Synthesized speech has been particularly successful for users who are blind or partially sighted, offering them an accessible output medium through screen readers.
Q63.
What do screen readers do in the context of synthesized speech?

a.

Provide predefined messages for quick communication

b.

Read only the text on the computer screen

c.

Produce natural speech with minimal user input

d.

Read the contents of the screen, including icons and menus

Discuss
Answer: (d).Read the contents of the screen, including icons and menus Explanation:Screen readers are software packages that read the contents of a computer screen, including icons, menus, punctuation, and controls, using synthesized speech.
Q64.
In what scenario is speech synthesis most challenging as a communication tool?

a.

When used with graphical interfaces

b.

When delivering predefined messages

c.

When used by computer literate individuals

d.

When assisting people with physical disabilities affecting speech

Discuss
Answer: (d).When assisting people with physical disabilities affecting speech Explanation:Speech synthesis is most challenging as a communication tool when assisting people with physical disabilities affecting speech, as the output needs to be natural with minimal input effort from the user.
Q65.
How can speech synthesis enhance applications where the user's visual attention is focused elsewhere?

a.

By providing visual content alongside synthesized speech

b.

By using predefined messages for quick communication

c.

By delivering monotonic and non-prosodic tones

d.

By delivering warnings and alerts through speech

Discuss
Answer: (d).By delivering warnings and alerts through speech Explanation:Speech synthesis can enhance applications where the user's visual attention is focused elsewhere, such as warnings in aircraft cockpits and cars, by delivering warnings and alerts through speech.
Q66.
What is the benefit of using fixed pre-recorded messages in the interface?

a.

They can be recognized by computers for accurate interaction.

b.

They provide real-time communication between users.

c.

They have natural human prosody and pronunciation.

d.

They require minimal processing power to function.

Discuss
Answer: (c).They have natural human prosody and pronunciation. Explanation:Fixed pre-recorded messages have natural human prosody and pronunciation, which can enhance the communication experience in the interface.
Q67.
How can recordings of users' speech be useful in collaborative applications?

a.

They can replace visual information entirely.

b.

They can be used for automated recognition by computers.

c.

They can be attached to documents as audio annotations.

d.

They can be used for generating real-time communication.

Discuss
Answer: (c).They can be attached to documents as audio annotations. Explanation:Recordings of users' speech can be attached to documents as audio annotations, allowing users to communicate with others or remind themselves about the content of the document at a later time.
Q68.
What happens when you simply play an audio recording faster?

a.

The pitch remains the same, but the volume increases.

b.

The pitch rises, but the comprehensibility decreases.

c.

The pitch remains the same, but the recording becomes distorted.

d.

The pitch and volume both increase proportionally.

Discuss
Answer: (b).The pitch rises, but the comprehensibility decreases. Explanation:When you simply play an audio recording faster, the pitch rises, but the comprehensibility of the speech decreases, making it less intelligible.
Q69.
How can digital signal processing techniques address the issue of accelerated speech?

a.

They can increase the pitch while keeping the same speed.

b.

They can accelerate speech while maintaining the same pitch.

c.

They can increase both the speed and the pitch proportionally.

d.

They can reduce the speed while maintaining the same pitch.

Discuss
Answer: (b).They can accelerate speech while maintaining the same pitch. Explanation:Digital signal processing techniques can accelerate speech while maintaining the same pitch, allowing for increased playback speed without affecting comprehensibility.
Q70.
In what scenario can accelerated playback of speech recordings be beneficial?

a.

During a live conversation with a user

b.

In collaborative applications with real-time interaction

c.

In telephone help desks with pre-recorded messages

d.

When attaching audio annotations to documents

Discuss
Answer: (c).In telephone help desks with pre-recorded messages Explanation:Accelerated playback of speech recordings can be beneficial in scenarios like telephone help desks with pre-recorded messages, where the message playback can be sped up to convey information to the operator more efficiently.
