The term "Swedish eech" is a phonetic term that refers to a specific sound in the English language. This term is commonly used by linguists and language teachers. The spelling of this term is determined by the International Phonetic Alphabet (IPA), which represents speech sounds. In IPA, the Swedish eech is represented by the symbol "ɛː", which indicates a long, open-mid front unrounded vowel. This sound is commonly found in the Swedish language and is often used in English as well, especially in British accents.
