Marathi as spoken in Mumbai
Bambaiya Hindi-Marathi contact speech with constant three-way switching; the densest code-mixing environment in India.
Mumbai and Pune speech mixes Marathi, Hindi, and English in the same sentence. Marathi-only recordings collected in Pune under-represent the Mumbai reality of tri-lingual switching.
Recruitment here

A representative Marathi cohort should be split roughly 40% western Maharashtra, 25% Vidarbha, 20% Marathwada, 15% Konkan rather than concentrated in Pune.

Studio setup
Treated booths in the western suburbs with parallel session capacity for multi-speaker conversation work.
