What is Text-to-Speech (TTS) generation?

Text-to-Speech generation is a technology that converts written text into spoken voice. It helps computers talk to us in a natural way.

beginner

Name two main parts of a typical Text-to-Speech system.

The two main parts are: 1) Text analysis, which breaks down and understands the text, and 2) Speech synthesis, which creates the actual sound from the text.

What is the role of a neural network in modern TTS systems?

Neural networks learn patterns of human speech from data and generate natural-sounding voices by predicting audio waveforms or spectrograms from text.

intermediate

Why is prosody important in Text-to-Speech generation?

Prosody includes rhythm, stress, and intonation in speech. It makes the generated voice sound natural and expressive instead of flat and robotic.

intermediate

What metric can be used to evaluate the quality of TTS output?

Mean Opinion Score (MOS) is often used. It asks human listeners to rate how natural and clear the speech sounds on a scale, usually from 1 to 5.

What does Text-to-Speech generation do?

A Translates text between languages

B Converts text into spoken voice

C Converts speech into text

D Generates images from text

Text-to-Speech generation turns written text into spoken words.

Which part of a TTS system creates the sound from text?

A Speech synthesis

B Language translation

C Data collection

D Text analysis

Speech synthesis is the part that generates audio from the processed text.

Why do modern TTS systems use neural networks?

A To learn speech patterns and generate natural voices

B To store large text files

C To translate languages

D To compress audio files

Neural networks help TTS systems produce more natural and human-like speech.

What does prosody affect in TTS output?

A The spelling of words

B The speed of text processing

C The size of the audio file

D The naturalness and expressiveness of speech

Prosody controls rhythm, stress, and intonation, making speech sound natural.

What is Mean Opinion Score (MOS) used for in TTS?

A Measuring text length

B Counting words in text

C Rating speech quality by human listeners

D Measuring audio file size

MOS collects human ratings to judge how natural and clear TTS speech sounds.

Explain how a Text-to-Speech system converts text into natural-sounding speech.

Think about how the system understands text and then creates voice.

Describe why prosody is important in making TTS voices sound human.

Consider how people speak with emotion and flow.
