Hindi Gave You 4 Free Spanish Sounds

Hindi and most Indian languages place the tongue against the teeth for T and D sounds. Spanish does exactly the same thing. Americans and British speakers place the tongue on the ridge behind the teeth — and have to retrain this habit for Spanish. You don't.

Indian English commonly uses a tapped R — the tongue quickly touches the ridge behind the teeth. This IS the Spanish single R in words like 'pero'. Most English speakers need to learn this from the 'butter' flap; you already do it naturally.

Hindi ण is produced in a similar palatal region to Spanish Ñ. While the exact articulation differs slightly, the tongue-palate contact pattern is familiar. Most English speakers have never made this sound before.

Indian English tends toward syllable-timed rhythm (each syllable gets roughly equal time), which is exactly how Spanish works. British and American English are stress-timed (some syllables are long, others are reduced to 'uh'). For Spanish, your natural rhythm is correct.
