Speech synthesis is the required output in which a machine reads out the words in a natural or simulated voice played via a loudspeaker. The technology is referred to as text-to-speech or TTS. It aims to convert natural language into speech. TTS is generally used as an accessibility feature to help those who face difficulty in reading digital texts. However, there are various other use cases that the TTS tool fulfills in different domains.

The TTS tools produce a computerized voice. However, with the advancement in technology, synthesized voices have become more sophisticated, and now it is much more natural sounding. It also helps to incorporate natural human inflections to render it more lifelike. TTS allows businesses to save time and money since it can generate sound automatically instead of going through the tedious process of manually recording the audio files.

Organizations can integrate text to speech online software into their business platform to apply TTS voice conversions and fulfill various tasks.

The TTS tool needs to cover the following essential steps for converting the text file into speech.

· Convert text to words: Primarily, the ML algorithm needs to convert text into a readable format. The textual file consists of inputs besides text, such as dates, numbers, abbreviations, and more. Even these inputs must be converted into readable format. It must be translated into words. The ML algorithm applies its framework to read the text with specific intonation. It takes note of punctuation and other structures inherent to the text.

· Complete phonetic transcription: The pronunciation of a sentence not only differs based on its structure, but it must also capture the meaning and emotional tone. The system has built-in dictionaries to read each sentence with the correct inflection. It uses general academic rules to create transcription if any word goes missing.  The algorithm deploys a suitable framework to accentuate the sentence correctly. It leverages the necessary data points from phrases and sentences to correct intonation.

· Convert transcription to speech: The TTS system uses an acoustic model to read aloud the processed text. Developing the proper intonation requires establishing a connection between sounds and phonemes. To read aloud, the system uses a sound wave generator.

What is the purpose of the TTS tool?

· TTS tools help to improve the accessibility of digital text. It makes it easier for those with visual impairments or reading difficulties to consume the online content.

· The TTS tool generally supports all popular languages. It allows you to select the language of your choice, input the text, and use the tool to convert the text into speed. Hence, the TTS tools can effectively read multiple languages.

· Businesses can use TTS tools to reach their target audience. They can use it in their video marketing strategy to give voice-over to their videos and make them more effective. It also helps localize the video and personalize it to attract and engage the ideal audience.

To Conclude:

The TTS tool is a trending assistive technology that is significantly changing human lives. The computer-generated voice with lifelike qualities serves various use cases in personal and commercial domains.
