The ModelTalker TTS system converts plain English text to speech. It uses a text to phoneme system which includes capabilities for parsing ToBI-like descriptions of the intonation. Synthesis is accomplished through a combination of database-driven speech and a variant on diphone-based phoneme to sound engines known as Biphone-Constrained Concatenation (BCC). Speech stored in the database encompasses common words and phrases in different contexts as well as a complete set of biphones. The BCC sound engine results in smoother, more natural speech, without sacrificing the ability to quickly "capture" new voices in the biphone inventories for the system.
Texts have been downloaded from this site, I have not seen the content of each of the speeches, but the overwhelming majority of these texts were told by Obama during his speeches. Anything else told by somebody else is negligible compared to the overall result of this analysis. According to Wikipedia The lexical diversity of a given text is defined as the ratio of total number of words to the number of different unique word stems.
While computer scientists have yet to build a working "universal translator" such as the one first described in the 1945 science-fiction novella "First Contact" and later employed by the crew of the Starship Enterprise on "Star Trek," the hurdles to creating one are being cleared. That is because the practical need for instant or simultaneous speech-to-speech translation is increasingly important in a number of applications. Take, for example, the hypergrowth of social networking and Skype chats that demand bidirectional, reliable, immediate translations. Similarly, when natural disasters strike, the problem of aid workers struggling to communicate with the stricken who often speak other languages can become overwhelming.
The unconventional Donald Trump may deliver a few surprises tonight when he gives his acceptance speech for the Republican nomination. It's hard to predict whether he'll go off script, but according to excerpts provided by the Trump campaign, he will attempt to unify his party -- a trend that appears in every Republican acceptance speech since at least Ronald Reagan's. In fact, there are several distinctive trends in word use during acceptance speeches. We selected the top 50 words used by each GOP nominee since 1980, compared and ranked them. The results reflect shifting priorities and messages.
The passages in question focus on lessons that Mrs. Trump, the wife of presumptive Republican presidential nominee Donald Trump, said she learned from her parents and the relevance of their lessons in her experience as a mother. They came near the beginning of her roughly 10-minute speech, which was otherwise distinct from the address that Mrs. Obama gave when her husband, then-Sen. Barack Obama, was being nominated for president.
