==Other glitches and notes==
*Typing in a four digit number will separate the tens (e.g. we pronounce 12:34 as "twelve thirty-four"). Anything above 5 digits and below is pronounced correctly, i.e., 54143 is pronounced "fifty-four thousand one-hundred forty-three". Four-digit numbers are pronounced correctly in Speakonia, however.
*Typing in "0000" results in Microsoft Sam saying "hundred" (he pronounces each digit separately in Speakonia, however, and first and last digits have snapping sound).
*If a word has an apostrophe in the pronunciation, then the Speakonian version of Sam will increase the pitch.
