The Importance of Text to Speech Technology

1. Introduction to Text to Speech Technology

Two things that help special people through their knowledge are giving them the right tools. Two data easy special and everywhere data above in will, by purpose. The introduce our his from and the purposes, technology. Nowadays, we can see some IT technology that can assist handicapped people who need it. This technology is very useful for them because they can get useful information without any experience or hard effort. This technology is called text to speech. Text to speech is often referred to as speech synthesis. Nowadays, the two terms are used interchangeably. This technology is the process of converting text input to audio. The idea is simple: it takes text input and out pops a spoken word. This will assist those who need it. In ancient history, this technology was not conducive. The voice was not clear and the sound was not so nice to hear. But after a long range of development, in this year the sound is not so different from the human voice. We can take the example of a trip communication system to search a path (GPS). The text to speech will give information at every turning point of the street until the destination. It will be very helpful because it is dangerous to take a look at the street while still enjoying the unseen scenery. Another very useful thing about this technology is that it helps blind people. They just need to get information from the internet and check if somebody has sent them an email.

2. Benefits of Text to Speech Technology

A TTS system can benefit the blind and partially sighted, but can also be a valuable tool for those with learning disabilities such as dyslexia. The support that a TTS system may provide could greatly increase the opportunities available to these groups, allowing fuller access to education and employment. TTS has long been a vital tool for the blind. Synthesized speech provided by TTS has enabled blind computer users to access the internet, open up new employment opportunities, and allowed them to fully integrate with the rest of society. In the past, it was often the case that the visually impaired would have to rely on a third party to read text for them. This is not only a barrier to independence but may also mean that personal or sensitive materials could not be accessed in private. By using TTS to convert text to audio and then adjusting the pitch, speed, and even the accent of the synthesized speech, the information may be presented in a way that is easier to understand. This provides a valuable service for those with learning difficulties. Dyslexic children and adults may have access to readers for particular exams or tasks but do not have access to this support for their own private study. TTS can provide the opportunity for continuous private study.

3. Applications of Text to Speech Technology

As stated in the introduction, TTS technology has played an important role in the development of other technologies in that era. The progress of TTS technology has opened up many opportunities for other fields to adapt and develop the technology. There are a lot of fields or applications that could use TTS technology as a service or apply it to their products in order to increase value and help solve problems. TTS technology is very applicable to be used for medical purposes. As we all know, medical fields have limited time to take a rest and read documents. The doctor could simply convert the text into speech and then listen to it while doing other activities. By doing this, the efficiency of work in medical fields could be increased. During this time, TTS could also be used to help blind people. By changing the text into speech, it will help them understand or get some information regarding a certain document. Other than that, automation systems are also a suitable place to apply TTS technology. In recent years, many companies are trying to replace their customer service with intelligent virtual agents. By using TTS, these agents could speak to the customer in a more natural way than previously using TTS technology that was available at that time. This could attract more customers to use the service and reduce the cost.

4. Limitations and Challenges of Text to Speech Technology

Unlike the artificial synthesis of human speech, the ability for humans to converse and communicate ideas is quite complex and requires an extraordinary amount of intelligence and experience. Human conversational speech is a very complex and multi-levelled communication process, consisting of information at the linguistic level, as well as information at the para-linguistic level (information that is connoted by, but is not part of the speech signal, such as the speaker’s mood or tempo of speech), and information at the extra-linguistic level, such as facial expressions and body gestures. The quality of text-to-speech systems is judged by how closely they approach the naturalness and expressiveness of human speech. While there has been much advancement in the state of the art for text-to-speech systems over the past few decades, significant progress still needs to be made before all systems approach the desired quality level for naturalness and expressiveness. Due to the complex nature of speech and the many levels of information that it carries, this is a very difficult goal to achieve and it is very hard to define exactly what is meant by naturalness and expressiveness in the TTS context. This makes it hard to measure progress towards these goals and there is still much research being done to find out exactly what is the best way to generate each aspect of speech. Another challenge facing TTS systems is the ability to synthesise speech in different languages. With ever-increasing globalization, there is a demand for speech synthesis systems in many languages. The quality of speech synthesizers varies significantly between different languages and some languages are not well supported at all. The current best TTS systems are generally for English and some have been developed for languages such as Spanish or Mandarin, however, for the majority of other languages, there are no good TTS systems available. It is a difficult and expensive task to develop TTS systems for a new language due to the need for much language-specific research and the recording of large amounts of speech. This means that there is likely to always be a shortage of TTS systems for smaller languages and some languages may never be well supported.

5. Conclusion: Embracing the Power of Text to Speech Technology

A host of academic papers have been written on the benefits of TTS (text to speech). The two fields, audio presentation and multimedia, have shown in both fact and fiction that TTS has a positive impact on people’s lives. Like a visual information system can enhance a customer’s response to a system, a multimedia information system might enhance learning and comprehension in a complex range of topics. In the research, “Does voice and video information increase computer self-efficacy of drill,” it was found that TTS rendering of on-screen text combined with video speech has a significant positive impact on perceived self-efficacy compared to text-based and graphical presentation. These results suggest that students use TTS to read out text to facilitate learning processes that would be otherwise difficult and as a result build confidence in their understanding of the topic. Given how often on-screen TTS information is used across various devices and software, one can expect that TTS technology played a significant part in the increase of self-efficacy of TTS practice group in comparison to the other two groups. High results in self-efficacy are often associated with subsequent improvements in academic achievement and effort.
