To achieve these sounds, curl the tongue back and touch the tip to the roof of the mouth. They are closer to the latter (retroflex), so when Marathi speakers say or speak English words containing t or d, they almost always use the retroflex version. The English consonants "t" and "d" fall somewhere in between the Marathi consonants t and d, and ṭ and ḍ.The consonant ch is virtually indistinguishable from c to the untrained English speaker, but is indeed a different letter. The consonant written 'c' can be confusing it is pronounced like the first sound in the word chair but without aspiration.In other words, a Marathi k sounds like an English "k" (without aspiration).
Marathi language has got two new vowels ॲ and ऑ due to the use of English language.
