AI-102 Exam - Question 173


You are developing an app that will use the text-to-speech capability of the Azure AI Speech service. The app will be used in motor vehicles.

You need to optimize the quality of the synthesized voice output.

Which Speech Synthesis Markup Language (SSML) attribute should you configure?

Show Answer
Correct Answer: AB

To optimize the quality of the synthesized voice output, especially in specific environments like motor vehicles, the style attribute of the mstts:express-as element should be configured. This attribute allows the adjustment of speech styles to suit various contexts and devices, ensuring clarity and quality. Attributes like pitch in the prosody element and level in the emphasis element do not directly address optimizing overall quality for specific environments such as vehicles.

Answer is correct: The audio effect processor that's used to optimize the quality of the synthesized speech output for specific scenarios on devices. For some scenarios in production environments, the auditory experience might be degraded due to the playback distortion on certain devices. For example, the synthesized speech from a car speaker might sound dull and muffled due to environmental factors such as speaker response, room reverberation, and background noise. The passenger might have to turn up the volume to hear more clearly. To avoid manual operations in such a scenario, the audio effect processor can make the sound clearer by compensating the distortion of playback. The following values are supported: eq_car – Optimize the auditory experience when providing high-fidelity speech in cars, buses, and other enclosed automobiles. eq_telecomhp8k – Optimize the auditory experience for narrowband speech in telecom or telephone scenarios. You should use a sampling rate of 8 kHz. If the sample rate isn't 8 kHz, the auditory quality of the output speech isn't optimized.
