New benchmark evaluates Indic TTS accent fidelity across six dimensions

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced PSP, a new benchmark designed to evaluate the accent accuracy of text-to-speech (TTS) systems for Indic languages. Unlike existing metrics that focus on intelligibility and naturalness, PSP specifically measures accent by decomposing it into six distinct dimensions, including retroflex collapse and prosodic signature divergence. Initial testing on systems like ElevenLabs v3 and Sarvam Bulbul revealed that top-performing systems in terms of word error rate do not necessarily excel in accent fidelity, highlighting the need for more nuanced evaluation methods.

    PSP: An Interpretable Per-Dimension Accent Benchmark for Indic Text-to-Speech

    Standard text-to-speech (TTS) evaluation measures intelligibility (WER, CER) and overall naturalness (MOS, UTMOS) but does not quantify accent. A synthesiser may score well on all four yet sound non-native on features that are phonemic in the target language. For Indic languages,…
