If you work in tech, sales or support, you say things like v2.3.1, RTX 4090 or Wi-Fi 6E aloud every day, but nobody teaches you how. These names follow their own spoken conventions in American English. Here are the rules, a big written-to-spoken table and a self-test.
1. Software version numbers
The dot in a version number is said as point. So v2.3.1 is "version two point three point one" (/ˈvɝːʒən tuː pɔɪnt θriː pɔɪnt wʌn/). Developers also say "two dot three dot one", but "point" is the safer choice; keep "dot" for domain names ("github dot com").
- 1.0: "one point oh" is most natural; "one point zero" is a bit more formal.
- 0.9: "zero point nine" or "oh point nine".
- 3.10 vs 3.1: different versions must sound different. Say "three point ten" for 3.10, "three point one" for 3.1, never "three point one oh".
- 2.x: the wildcard is read as the letter: "two point x" (/tuː pɔɪnt ɛks/).
Semantic versioning: major /ˈmeɪdʒɚ/, minor /ˈmaɪnɚ/, patch /pætʃ/. Pre-release labels: alpha /ˈælfə/, beta /ˈbeɪtə/ (American, not "beeta"), RC = "R C" or "release candidate".
2. Product model names
The core rule: two-digit numbers are said as ordinary numbers; longer numbers are split into pairs.
- iPhone 15 Pro Max: "iPhone fifteen Pro Max". Galaxy S24: "Galaxy S twenty-four".
- PlayStation 5: "PS five". Windows 11: "Windows eleven".
- RTX 4090: "R T X forty ninety".
- Boeing 737: "seven thirty-seven" (one digit plus a pair).
- Porsche 911: "nine eleven" (but emergency 911 is "nine one one").
- M2 chip: "M two". Core i7: "i seven". Wi-Fi 6E: "Wi-Fi six E". USB-C: "U S B C" (the hyphen is silent).
Years pair up too: 2024 is "twenty twenty-four". A zero inside a code is often "oh" (X0 = "X oh"); use "zero" when precision matters.
Say the letters the American way
Letters are spelled out with the English alphabet. These cause most of the trouble:
- A /eɪ/, E /iː/, I /aɪ/
- G /dʒiː/ vs J /dʒeɪ/
- H /eɪtʃ/, R /ɑːr/, Y /waɪ/, Z /ziː/ ("zee" in American English)
3. Part numbers and SKUs
Read AB-4471/X_02 in chunks of two or three with a pause between them: "A B, dash, forty-four seventy-one, slash, X, underscore, oh two." Symbol names:
- - "dash"
- / "slash"
- _ "underscore"
- Say "capital A" and "lowercase b" when case matters.
On a noisy line, clarify with "as in": "B as in Bravo".
| Letter | Say | Letter | Say |
|---|---|---|---|
| A | Alpha | N | November |
| B | Bravo | O | Oscar |
| C | Charlie | P | Papa |
| D | Delta | Q | Quebec |
| E | Echo | R | Romeo |
| F | Foxtrot | S | Sierra |
| G | Golf | T | Tango |
| H | Hotel | U | Uniform |
| I | India | V | Victor |
| J | Juliet | W | Whiskey |
| K | Kilo | X | X-ray |
| L | Lima | Y | Yankee |
| M | Mike | Z | Zulu |
4. Sizes and specs
- 256GB: "two fifty-six gigabytes" or, casually, "two fifty-six gigs". 16GB RAM: "sixteen gigs of RAM" (RAM rhymes with ham).
- 5G: "five G". 3.5mm jack: "three point five millimeter jack".
- 27-inch: "twenty-seven inch" (singular before a noun).
- 120Hz: "one twenty hertz" /hɝːts/.
- 10x zoom: "ten x zoom" (the x is the letter, not "times").
5. Where the stress goes
The last element usually carries the main stress, because it is the distinguishing information:
- iPhone fifteen PRO (and iPhone fifteen Pro MAX)
- U S B C
- version TWO point three (later digits are lighter unless contrasted)
- Model THREE, R T X forty NINETY
The big table: written to spoken
| Written | Say it | Notes |
|---|---|---|
| v2.3.1 | version two point three point one | "point" for versions |
| 1.0 | one point oh | "one point zero" is fine too |
| 3.10 | three point ten | not the same as 3.1 |
| 2.x | two point x | x is the letter |
| RTX 4090 | R T X forty ninety | four digits in pairs |
| Wi-Fi 6E | Wi-Fi six E | E = /iː/ |
| 1080p | ten eighty p | p is the letter |
| AB-12_c | A B dash twelve underscore lowercase c | chunk and pause |
