It is also possible to convert the speed of audio read slowly and carefully. Since it can be generated repeatedly, it is possible to create audio data files with accurate pronunciation and emotion in the voice.

Synthesize Voices to Read Loud

Since you can create narration in your own voice and create content from it, it can be used in a wide range of businesses using voice. When giving presentations or lectures, some companies use speech synthesis sites or apps to generate your own voice in advance. This has the advantage that you can ask and answer questions from other people at the same time because you can speak for them even if you don't actually speak.

Even if you lose your voice, you will always speak with your own voice

If you use a free speech synthesis site, you can extract only your own voice and save it as data. Even if you lose your voice due to illness, etc., you can not only reproduce your own voice, but depending on the app, you can input text and make it speak.

Reading the closing address at the funeral in the person's voice before death

When a loved one dies, isn't it difficult to put it into words yourself? There may be times when you have to speak at a funeral, even if it is painful. If you use AITalk, the app will imitate your voice and read it out loud for you.

Deliver messages in your own voice for important anniversaries, ceremonial occasions, etc.

Have you ever been so overcome with emotion that you were unable to express your feelings when you wanted to express your feelings to a large group of people, such as at a wedding? If you use a free speech synthesis site, you can synthesize your own voice and add your feelings to it to make it speak.

Deliver Messages in Your Own Voice

Keep your old young voice and speak anytime

Your voice changes as you get older. Current voices have a limited lifespan, so use a speech synthesis app or free software to save your own voices. It is possible to hear your young voice no matter how many years pass.

You can give lectures and presentations using your own voice

Is there anyone who doesn't like speaking in front of a large number of people? AITalk can also be used in situations where you must give a lecture or give a speech that you must not fail at. The advantage of speech synthesis apps is that they can convey accurate information without causing misunderstandings.

Give Lectures and Presentations in Your Own Voice

Recording Tips for Synthesizing Your Own Voice

This is a basic point, but it is important to do it in a quiet environment when recording. Also, depending on the reading software or app, please note that extremely short audio data may not be usable. In order to create a natural sound that does not convey a synthetic feel, it is best to pronounce it a little more exaggeratedly than in normal conversation. When compositing, it depends on the quality of your own voice, so we recommend having a third party check it before recording.

Tips for Synthesizing Your Own Voice

Also, if you are going to write a text or create a narration, be sure to have a manuscript ready. Just by recording your voice in a way that makes it easier for the other party to hear you, the way the receiver perceives your voice will change dramatically.

Conclusion

Your voice is a great tool to convey your emotions to others. If you can use audio freely, you can create content that connects more people. Nowadays, you can easily synthesize your own voice if they have speech synthesis software. Although some of them are paid, some sites and apps can be used for free (for example, Vidnoz AI), so if you are interested, why not give them a try?
