Pronounce it as two syllables: /ˈɔː.toʊ/ in US, with the first syllable stressed. In practice, say AH-TOH, but keep the second syllable quick and light: auto. IPA guidance helps: US /ˈɔː.toʊ/, UK /ˈɔː.təʊ/, AU /ˈɒː.təʊ/. Focus on a clear open first vowel, then a clipped second syllable. Audio references: you can compare with pronunciations on Forvo or YouGlish for native speakers.
Common errors include: (1) over-articulating the second syllable, turning auto into AW-toh; (2) replacing the first vowel with a shorter sound like /æ/ or /ɪ/ instead of /ɔː/ or /ɔː/; (3) misplacing stress, saying a weak first syllable. Correction tips: keep the first syllable with a long open /ɔː/ or /ɒː/ sound and stress it, then release a short, almost unstressed /tə/ or /toʊ/ second syllable. Record yourself and compare to native samples to self-correct.
US English typically has a strong, stressed first syllable /ˈɔː.toʊ/. UK English often uses /ˈɔː.təʊ/, with a slightly shorter second syllable and non-rhoticity in some regions; some speakers may reduce to /ˈɔː.tə/. Australian English tends toward /ˈɒː.təʊ/ with a more centralized second vowel and a clipped second syllable. Rhoticity in US does not affect auto much since the word itself is non-rhotic in practice, but the rhoticity of the broader phrase can influence surrounding vowels.
The difficulty lies in balancing a long, tense first vowel with a quick, reduced second syllable, and preserving natural linking in phrases like auto industry. The first syllable requires a relatively open, rounded mouth shape; the second syllable often reduces to a schwa-like or /ə/ or /toʊ/ depending on accent. Getting the exact vowel height and lip rounding for /ɔː/ vs /ɒː/ in different dialects is tricky, as is maintaining the contrast with words like autumn or author in connected speech.
Is all of the second syllable fully pronounced, or is it common to reduce to /tə/ in rapid speech? In natural American speech, many speakers reduce the second syllable to a quick, almost unstressed /tə/ or /toʊ/ depending on tempo and surrounding words. The primary cue remains the stressed first syllable and a clear first vowel /ɔː/. Ensure the second syllable does not vanish entirely in careful speech, but in quick conversation, a light /tə/ or /toʊ/ is very typical.

Auto derives from the short form of automobile, which itself comes from the French auto- + mobile, from Greek aut- meaning self (auto) and Latin mobilis meaning movable. The automobile term began to appear in the mid-19th century as engineers connected the idea of self-powered machines to wheel-based vehicles. The root auto- (self) traces to Greek autos, with the Latin mobilis becoming central to the sense of ‘able to move’. By the late 19th and early 20th centuries, ‘automobile’ became common, while ‘auto’ emerged in colloquial speech and industry jargon (auto shop, auto insurance). The word’s popularity surged with the rise of personal cars in the 20th century, and the clipped form remains prevalent in American and global English as a casual, efficient referent for cars and related domains. First known uses appear in transportation literature and inventor/apparel industry catalogs; by the 1920s, auto was widely understood as shorthand for automobile. Today, auto is a widely recognized lexical item in modern English, especially in North American speech.
