Why Are English Consonant Sounds Important?
English pronunciation can be tricky because spelling does not always match sound. Many letters or letter combinations can represent different sounds.
- Learning the correct sounds helps you speak more clearly.
- It also helps you understand native speakers better.
- Some sounds, like /θ/ そして /ð/, are unique to English and can be challenging for Spanish speakers.
Voiced vs. Voiceless Consonants: What's the Difference?
Many English consonant sounds come in pairs: one is 'voiceless' and the other is 'voiced'.
- Voiceless sounds: Your vocal cords do not vibrate. Try saying /s/. You only hear air.
- Voiced sounds: Your vocal cords vibrate. Try saying /z/. You should feel a vibration in your throat.
- This difference is crucial for distinguishing words like 'sip' そして 'zip'.
The Tricky 'TH' Sounds: /θ/ and /ð/
These two sounds are often difficult because they don't exist in Spanish. Both use the 'th' spelling.
- /θ/ (Voiceless 'th'): This sound is like a soft 's' but with your tongue between your teeth. Air flows out.
- Common spellings: th （例：, think, bath)
- /ð/ (Voiced 'th'): This sound is similar to /θ/, but your vocal cords vibrate. It's like a soft 'd' or 'z' with your tongue between your teeth.
- Common spellings: th （例：, this, mother)
S and Z Sounds: /s/ and /z/
These sounds are very common. The main difference is voicing.
- /s/ (Voiceless 's'): This is the sound you make in words like 'say'. It's similar to the 's' in Spanish.
- Common spellings: s, ss, c (before e, i, y) (e.g., sun, pass, city)
- /z/ (Voiced 'z'): This sound is like a buzzing 's'. Your vocal cords vibrate.
- Common spellings: z, s (between vowels or at the end of plural nouns/verbs) (e.g., zero, music, dogs)
SH and ZH Sounds: /ʃ/ and /ʒ/
These are 'sh' and 'zh' sounds. /ʃ/ is common, but /ʒ/ is less frequent.
- /ʃ/ (Voiceless 'sh'): This sound is like telling someone to be quiet. Your tongue is near the roof of your mouth.
- Common spellings: sh, ch (in some French loanwords), ti, ci, ssi （例：, shop, chef, nation, special, mission)
- /ʒ/ (Voiced 'zh'): This sound is the voiced version of /ʃ/. It's less common and often found in words from French.
- Common spellings: s (between vowels), si, ge （例：, usually, measure, garage)
CH and J Sounds: /tʃ/ and /dʒ/
These are 'ch' and 'j' sounds, which are 'affricates' (a stop followed by a fricative).
- /tʃ/ (Voiceless 'ch'): This sound is like the 'ch' in Spanish 'muchacho'.
- Common spellings: ch, tch （例：, choose, watch)
- /dʒ/ (Voiced 'j'): This sound is the voiced version of /tʃ/. It's like the 'j' in 'jeans'.
- Common spellings: j, g (before e, i, y), dg （例：, jeans, gym, bridge)

練習
スペイン語話者がよく犯す間違い
Spanish speakers often make these mistakes with English consonant sounds:
- 'Th' sounds (/θ/, /ð/): Replacing them with /t/, /d/, 、または /s/. For example, saying "tink" ～の代わりに "think", 、または "dis" ～の代わりに "this." Remember to put your tongue between your teeth.
- 'Z' sound (/z/): Pronouncing it like an /s/. For instance, saying "sue" ～の代わりに "zoo." Feel the vibration in your throat for /z/.
- 'Sh' (/ʃ/) and 'Ch' (/tʃ/): Confusing these sounds. For example, saying "watch" ～の代わりに "wash." について /tʃ/ sound has a clear 't' at the beginning.
- 'J' (/dʒ/): Replacing it with /j/ (like the 'y' in "yes") or /tʃ/. For example, saying "yoke" ～の代わりに "joke." について /dʒ/ sound is a strong, voiced 'j'.
よくある質問
How can I practice the 'th' sounds?
Practice by placing your tongue gently between your front teeth. For /θ/, push air out. For /ð/, do the same but make your vocal cords vibrate. Say words like "think" そして "this" slowly.
What is the difference between /s/ and /z/?
The main difference is voicing. /s/ is voiceless (just air), like in "sip." /z/ is voiced (vocal cords vibrate), like in "zip." Feel your throat to check.
Are there minimal pairs for these sounds?
Yes, minimal pairs are great for practice! Examples include "thin" 対. "tin" (/θ/ 対. /t/), "sip" 対. "zip" (/s/ 対. /z/), and "share" 対. "chair" (/ʃ/ 対. /tʃ/).
How can I distinguish between /ʃ/ and /ʒ/?
Both sounds are made with your tongue near the roof of your mouth. /ʃ/ is voiceless (e.g., "shop"), while /ʒ/ is voiced (e.g., "usually"). Focus on whether your vocal cords vibrate.
