Claim 1: “Today’s computers use machine learning, a kind of artificial intelligence, to sound like a person.”
INSUFFICIENT EVIDENCE
No evidence was provided in the search results to verify the use of machine learning in modern TTS systems.
Claim 2: “If a computer wants to say “Hello, how are you?” it breaks each word into bits of sound called phonemes.”
SINGLE SOURCE
The provided evidence for this claim consists of search results for 'text messaging' and 'texting apps', which are irrelevant to the technical process of text-to-speech phoneme breakdown.

Claim 3: “Way back in the 1700s, inventors tried to make machines work like your lungs and throat do. They used bellows... to push air from inside the bag through pipes, whistles and leather tubes.”
VERIFIED BY REFERENCE
Web search results confirm that 18th-century inventors like C.G. Kratzenstein and Wolfgang von Kempelen created 'talking heads' using organ pipes and other mechanical means to simulate human speech.

Claim 4: “This advanced technology even allows a sophisticated AI computer to listen to a recording of your voice for just a few seconds, learn your exact speech patterns and copy it.”
INSUFFICIENT EVIDENCE
No evidence was provided in the search results to verify the specific claim regarding voice cloning from a few seconds of audio.
Claim 5: “One famous machine was called Voder, which made its debut at the 1939 World’s Fair in New York City.”
VERIFIED BY REFERENCE
Wikipedia explicitly confirms that the Voder (voice operating demonstrator) was invented by Homer Dudley and debuted at the 1939 New York World's Fair.

Claim 6: “When you speak, your lungs push air up your windpipe and through the vocal cords in your throat. That makes the vocal cords vibrate, which creates sound.”
INSUFFICIENT EVIDENCE
No evidence was provided in the search results to verify the biological process of speech production described in the claim.
Claim 7: “older software programs had to stitch together small sounds that had been mapped out from recorded voices. The maps, called spectrograms, look like graphs with peaks and valleys representing how strong each tone was”
CORROBORATED
Web search results confirm that spectrograms are used to visualize the pitch, volume, and timbre of speech and have a history in speech acoustics dating back to the late 1800s.
