Speech Synthesizer facts

While investigating facts about Speech Synthesizer Online and Speech Synthesizer App, I found out little known, but curios details like:

Stephen Hawking once dined in the company of Edward Teller,pioneer of the hydrogen bomb, and typed "He is Stupid" in his speech synthesizer without bothering to lower the volume

how speech synthesizers work?

In 2014 Intel worked with Stephen Hawking to upgrade the program he uses to talk to the world, but he refused to change the speech synthesizer board that gives him his iconic voice.

Speech synthesizers use what to determine context?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is a speech synthesizer. Here are 10 of the best facts about Speech Synthesizer C# and Speech Synthesizer Vst I managed to collect.

what do speech synthesizers use to determine context?

1. Synthesized voices like Siri aren't synthesized from scratch. Instead, parts of speech recorded by voice actors are stored in a database and effectively combined by text to speech systems to form words and sentences not actually recorded by the actor.

2. Stephen Hawking's famous speech synthesizer is actually based off it's creator (MIT researcher Dennis H. Klatt) own voice.

3. Stephen Hawking married the ex-wife of the man who first designed his speech synthesizer.

4. Some Chryslers from the mid-1980's had an "Electronic Voice Alert" system that would use a Speak & Spell-esque speech synthesizer to warn the driver about any problems the car was having.

5. The 'BrailleNote' portable device has a Braille keyboard, a speech synthesizer, and most importantly a refreshable Braille display, all combining to allow people with visual impairments portable access to information such as the internet and school text books.

6. A single experimental recording was made in 1939 by Bell Labs through their Vocoder transatlantic signal processor. Audio pioneers like Bruce Haack developed musical vocoders in the late 60s into the now common "robot voice," auto-tune, and synthesized speech.

7. The 'Voder' was the first attempt to electronically synthesize human speech by breaking it down into its acoustic components. It debuted at the 1939 New York World’s Fair and was operated by a 'Voderette' who used keys and pedals to generated a synthesized voice in realtime.

8. The company that created Stephen Hawking's speech synthesizer went into liquidation and lost its original software. Hawking identifies so heavily with his distinctive voice that he shunned a more natural-sounding replacement and instead bought the last three remaining machines.
