Indian English ASR is automatic speech recognition optimised for Indian English accents, regional pronunciation patterns, and common Hindi-English code-mixing — so voice hiring tools transcribe candidate speech accurately instead of producing word errors that derail interview follow-ups.
US-trained speech models often achieve strong word error rates on broadcast American English but degrade on Indian English phonology — different vowel lengths, syllable timing, and stress patterns. In a voice interview, a misheard answer triggers irrelevant follow-up questions, making candidates feel the system is not listening.
Code-mixed speech — Hindi or regional language words embedded in English sentences — confuses monolingual English models further. Contact center and BPO hiring pools across Bangalore, Pune, NCR, and tier-2 cities include diverse accent profiles; a model validated on one metro accent may fail elsewhere.
ASR word error rate is not an abstract metric in hiring — it directly affects interview integrity and fairness. Candidates judged on garbled transcripts receive lower scores for communication competencies they demonstrated correctly aloud.
Multilingual interview programmes may offer Hindi, English, or regional language options. Each language path needs its own ASR quality bar — switching language without switching model is a common failure mode.
Teams hiring across India should pilot voice screens with internal employees representing accent diversity before promising candidates a seamless AI interviewer experience. Intervues does not certify third-party ASR vendors; evaluate against your own candidate pool.
No. Indian English ASR targets English spoken with Indian accents. Hindi ASR targets Hindi speech. Code-mixed utterances may need models trained on both patterns.
Poor ASR systematically disadvantages accent groups if scores derive from flawed transcripts — a fairness issue distinct from human similarity bias.
Some products offer text fallback for connectivity or accessibility. Text measures written fluency, which may not match spoken job requirements for voice roles.
