Explain the speech generation method.

Speech generation, also known as text-to-speech (TTS), is a method used in multimedia to convert written text into spoken words. This technology is used to create audio output in various applications, such as virtual assistants, GPS systems, and audiobooks.

The process of speech generation involves several steps. First, the written text is analyzed by a TTS system, which breaks it down into small units called phonemes. Phonemes are the smallest units of sound that make up words in a language.

Next, the TTS system applies rules of pronunciation and intonation to the phonemes based on the language being spoken. This is called phonetic analysis. The system uses a database of pre-recorded speech sounds to create a speech waveform for each phoneme, which is then combined to create a full sentence.

The final step is to convert the speech waveform into an audio file that can be played back by a computer or other device. This can be done using various compression techniques to reduce the file size while maintaining the quality of the sound.

Overall, speech generation is a method used in multimedia to convert written text into spoken words. It involves analyzing the text, breaking it down into phonemes, applying pronunciation and intonation rules, and creating a speech waveform, which is then converted into an audio file.
