VOICE SYNTHESIS TECHNOLOGY 2025: SAVE 80% OF VIDEO PRODUCTION TIME

Speech Synthesis is a field of artificial intelligence (AI) that allows computers to generate artificial voices from text. This technology is being widely applied in many different fields, bringing many benefits to people's lives.

Principle of operation

Speech synthesis technology works on algorithms and machine learning models to convert text into audio. This process typically includes the following steps:

● Text analysis: The system will analyze the context of the input text, decode the meaning, and sentence structure to ensure that the generated voice is appropriate for the content.

● Text-to-phoneme conversion: Each character or word in the text will be converted into basic sound units, or phonemes, to form the basis for pronunciation.

● Sound Generation: Using voice data collected from real people or voices synthesized using technology, the system will combine the converted phonemes in the correct text sequence, creating a complete voice simulation sound.

It can be seen that how "real" the quality of the voice will depend on the software's ability to understand the context and, above all, the ability to synthesize the software's voice.

Application of voice synthesis technology

● Assistive Technology: The outstanding application of text-to-speech technology lies in its ability to assist people with disabilities. According to statistics from the World Health Organization (WHO), it is estimated that about 2.2 billion people globally have visual difficulties. Text reading software helps visually impaired people easily access information. Instead of reading directly, they can listen to the content converted into audio, either by listening to the text on the device's screen or by scanning the paper text for the software to read aloud.

● Online Learning: Learning habits have changed since the pandemic. Now, online learning has become popular also thanks to its benefits. To enhance the effectiveness of this new learning method, many educators have started applying artificial voice generation technology. Instead of just using text, the combination of natural sounds helps students absorb knowledge in a more interesting way. In addition, studies have proven that learning through listening and remembering information plays an important role in strengthening and improving students' cognitive abilities.

● Marketing: This is a field that requires expensive resources for businesses. Taking advantage of AI voice helps businesses save time and money while still being able to convey their messages.

● Content production: Speech synthesis technology is opening up unique creative possibilities, especially in the field of multimedia content production. Instead of hiring a voice actor, you can use these tools to create YouTube videos, audiobooks, podcasts, and even musical compositions with lyrics.
