Artificial intelligence has played a key role in developing the technology that can convert simple text into voiceovers with a significant amount of human touch attached to it. Such voice overs are now more human-like than what most people expect text to speech conversions to be. The technology is only getting better with the advancement of AI. However, while using text to speech conversion technology, there are certain pointers that can help you produce even better quality voiceovers. A few of these pointers are discussed below-
Emphasizing each sentence- Converting several sentences into speech at once sometimes compromises the quality of sound. If you wish to improve the intonation and pause of the speech, you can work on one sentence at a time. This helps you in determining which word or phrase you want to emphasise and where you want pauses.
Adding pauses in the speech- Pauses create a natural-sounding speech basically because humans too take natural pauses to breathe while speaking. In order to bring more authenticity to the AI produced speech, you can add pauses in the form of full stops, commas, dashes etc. This helps in creating a more human-like AI voice over.
Using inventive spelling- Deep learning is susceptible to making mistakes in pronunciation while converting text to speech primarily because it works in a predictive manner. Therefore, there is a possibility that it will pronounce “read” in She can read and “read” in She hasn’t read the book in the same manner. To address this issue, you can spell such words phonetically. For example, in the first sentence, you can type “read” as “reed”. Furthermore, it is suggested to insert full stops in between the letters of an abbreviation, otherwise it will be pronounced as a single word. For example, you should type AI as A.I.
Emphasizing the words- The most intriguing aspect of human speech is the difference in the emphasis on each word. While we are speaking, we tend to change our tone and emphasize more on certain words to catch the attention of the audience. While converting text to speech, such emphasis can be added by either putting the word in quotation marks or by capitalizing it.
With the help of these pointers, you can bring more human touch to the speech generated without the involvement of an actual human being!
