Factual error: USS Enterprise's onboard computer initially refuses to acknowledge Chekov's authorization code. The reason, it seems, is Chekov's Russian accent, which pronounces the letter "V" (pronounced labiodentally) like a British "W" (pronounced bilabially). Problem: Chekov pronounces his ensign authorization code in the NATO phonetic alphabet. ("Nine, Five, Victor, Victor, Two", which resolves to 95VV2) This alphabet is specifically designed to alleviate this exact same situation. The 26 code words in the NATO phonetic alphabet are assigned to the 26 letters of the English alphabet: Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, and Zulu. The slightly mispronounced "Wictor" should not be a problem. (00:42:05)
Factual error: When the black hole consumes the planet Volcan and the scene shows the starship Enterprise flying off from the area and then showing the planet disappearing, the remaining image is space full of stars with a black circle in the middle without the stars, implying that the black hole is in the middle. This is false. If there was a black hole there, we would see a light corona from light distorting around the black hole; there is no scenario in which we would see a black circle blocking stars/light.

Suggested correction: You're applying today's standards to a fictional future. We've seen in every iteration of Star Trek that security includes both a passkey/password and voice authentication. The actual mistake here is that regardless of how Chekov speaks, the computer should recognize it as his voice because he always speaks that way.
I am afraid the computer's error message leaves no doubt that there was no voice matching at work this time; only pure speech-to-text.
