Speech synthesis is the artificial production of human speech, using a speech synthesizer implemented in software or hardware.
Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and it can be implemented in software or hardware. Speech synthesis can be driven by text-to-speech (TTS), where normal language text is converted into spoken output, or by other symbolic linguistic representations (such as phonetic transcriptions) that are rendered as speech. A speech synthesizer typically follows a pipeline with a front-end and a back-end. The front-end performs text processing such as text normalization/tokenization (e.g., expanding numbers and abbreviations), converts text to phonetic transcriptions (grapheme-to-phoneme or text-to-phoneme conversion), and adds prosodic structure (phrases, clauses, sentences) including timing and pitch targets. The back-end (the synthesizer) then converts this symbolic representation into an audio waveform, producing intelligible and natural-sounding speech.
Speech synthesis is the artificial production of human speech, using a speech synthesizer implemented in software or hardware.
TTS systems convert written text into speech, while other systems can convert symbolic linguistic representations (e.g., phonetic transcriptions) into speech.
Typical TTS architecture uses a front-end (text normalization, phoneme assignment, prosody/prosodic unit planning) and a back-end that generates the final sound waveform.
The artificial production of human speech.
A software or hardware system that generates speech for the purpose of speech synthesis.
A system that converts normal language text into spoken audio.
The part of a TTS system that normalizes text, assigns phonetic transcriptions, and determines prosodic structure.
The part of a TTS system that converts the symbolic linguistic representation (phonemes and prosody) into an audio waveform.
The process of converting raw text containing symbols like numbers and abbreviations into their spoken word equivalents.
The process of assigning phonetic transcriptions to words based on their spelling or written form.
Rhythmic and intonational aspects of speech such as phrase structure, pitch contour, and phoneme durations.
