Hinglish as spoken in Mumbai
Bambaiya Hindi-Marathi contact speech with constant three-way switching; the densest code-mixing environment in India.
Hinglish is the code-mixing case itself. Typical urban customer-support speech is 30-60% English tokens embedded in Hindi grammar, with switching several times per utterance.
Recruitment here
Migrant-heavy, so speakers of almost any Indian language can be found, but native-region screening is essential.
Recruit by switching behaviour, not by language proficiency. Screening recordings are used to confirm speakers switch naturally rather than performing one language.
Studio setup
Treated booths in the western suburbs with parallel session capacity for multi-speaker conversation work.
Hinglish quality rules
- Whether English tokens are written in Latin or transliterated into Devanagari must be fixed by rule, not left to annotators
- Language-ID tagging per token is required for training but is skipped by most vendors
- Ambiguous words shared by both languages need an explicit tie-break rule
Session types available
- Simulated customer-support calls with natural switching
- Two-party spontaneous conversation between colleagues
- Voice-assistant commands with English app and brand names
- Per-token language-tagged transcription
