You can also use neural voices to add personality and differentiation to your brand, product, or service. You can choose from a range of male and female voices in different languages and accents, and customize them further with your own custom model.
From written text to natural-sounding speech: The process
The process of converting written text to natural-sounding speech is as follows:
- The input text is analyzed and normalized by the service, which means that it is converted into a standard format that can be processed by the speech synthesis system. This includes resolving abbreviations, acronyms, numbers, dates, emoticons, and other symbols into words or phrases.
- The normalized text is then divided into sentences and words, and each word is assigned a part-of-speech tag and a stress pattern. The service also identifies the boundaries of phrases, clauses, and paragraphs, which are used to determine the prosody of the speech output, such as intonation, pitch, and pause.
- The service then converts each word into a sequence of phonemes, which are the smallest units of sound in a language. The service uses a combination of linguistic rules and data-driven models to determine the correct pronunciation of each word, taking into account the context, the dialect, and the user preferences. The service also uses the IBM Symbolic Phonetic Representation (SPR) to allow users to specify custom pronunciation for any word or phrase using the Speech Synthesis Markup Language (SSML).
- The service then generates the acoustic features of the speech output, such as pitch, duration, energy, and spectral envelope, using a deep neural network that is trained on human speech data. The service uses a different neural network for each language and voice, and can also use a custom model that is created by the user to fine-tune the speech output for their specific use case and target market.
- The service then synthesizes the speech waveform from the acoustic features using a vocoder, which is another deep neural network that is trained on speech waveforms. The service uses a different vocoder for each language and voice, and can also use a neural voice that is powered by deep neural networks trained on human speech to produce more expressive and natural speech that can convey emotions and tones.
- The service then returns the speech output as an audio file in WAV or OGG format that can be played or downloaded by the user. The user can also use SDKs for various programming languages to integrate the service into their projects more easily.
