Tones in real speech, and common mistakes

Tones don't disappear in fast speech. Every syllable keeps its tone; unstressed syllables just get shorter and lighter.

Stress at the end

English stresses words early: "BANG-kok". Thai puts the weight on the last syllable of a word or phrase: กรุงเทพgrung-têep, with the weight on têep. In ผัดไทยpàt-tai both syllables are full.

Keep English intonation out

A "question voice" that rises at the end can turn your last word into a rising tone, and a tired "statement voice" that drops can make a mid tone sound low. Let the words carry their own pitch.

The top ten mistakes

1. ไปbpai with a puff of air, like "pie". Say bpai.
2. Final stops released or dropped. บาทbàat ends in a quiet, held t.
3. คุณkun said long, like "koon". It's short.
4. Tone swaps: ใกล้glâi and ไกลglai, ใช่châi and ใช้chái, ข้าวkâao and ขาวkǎao, ห้าhâa and หาhǎa.
5. ครับkráp with a low tone. It's high.
6. ค่ะkâ in questions, คะká in statements.
7. Reading English spellings: Phuket is ภูเก็ตpuu-gèt (ph is a p, not an f), and Thai is ไทยtai, with no "th" sound.
8. English plurals: two coffees is กาแฟสองแก้วgaa-fae sǎwng gâew.
9. Pronouncing a silent leading h: หมาmǎa, not "ha-maa".
10. Every vowel at medium length.

Contractions you'll hear

• อย่างไรyàang-rai becomes ยังไงyang-ngai (how?)
• หรือเปล่าrǔue-bplàao becomes รึเปล่าrúe-bplàao (...or not?)
• ไหมmǎi often sounds like มั้ยmái

In fast speech เขาkǎo and ฉันchǎn often sound high, káo and chán. Both forms are understood.

Typical mistake: slowing right down to get the tones right, then rushing and losing them. Practise short phrases at natural speed until they feel automatic.
