My throat hurts and I can't speak / my voice won't come out

It's really troublesome when your throat hurts and you can't get your voice out.

Even though I have important meetings and fun plans with friends, I can't even speak!

AI voice is recommended

hello 930

When you can't speak because your voice is gone, AI voice is highly recommended.

AI voice technology is evolving every day, allowing you to communicate with natural-sounding speech.

It is truly a lifesaver for people who find it difficult to speak due to throat pain!

With AI voice, you can convey important information as your surrogate "voice" while resting your throat.

By using a smartphone or computer to have the AI speak what you want to say,

I can't speak because my voice is gone...

VTubers, voice actors, and others are using it too

In fact, the number of people using AI voice is rapidly increasing.

It provides great support not only when your throat is in bad condition but also for people in situations where speaking is difficult.

For example:

  • When you can't speak due to a cold
  • When you have a sore throat and can't make a sound

In such times, they use AI voice to communicate.

This is a perfect example of how technological progress is enriching people's lives.

Additionally, there are many cases where VTubers and voice actors use AI voice during video streams when they cannot speak after surgery or when they have developed laryngitis.

Thanks for the stream!
It was a novel stream using full text-to-speech (Ondoku).

(Yesterday's Getting Over It also looks interesting. I have to watch the archive.)

I hope Miko-chi's throat heals as soon as possible.
Take care! pic.twitter.com/bf3ZH913Nk

What is the reaction to AI voice from those around you?

You might wonder, "What will people around me think if I use AI voice?"

I really lost my voice so I'm using Ondoku to type on my phone and talk, but for some reason, everyone in my family listens better than when I speak with my own voice, it's strange lol especially my husband lol

I was playing with Ondoku with my younger brother and it's too funny LOL

My throat hurts and my voice won't come out at all, so I'm relying on Ondoku again.
Ondoku is very helpful when lip-syncing and hand gestures don't get through to my son.
Thank you Ondoku......https://t.co/G3vw5Kp6EN
