ViTone: A Diagnostic Benchmark for Tonal Faithfulness in Vietnamese Text-to-Speech

2026-08-18

Abstract excerpt

<title>Abstract</title> <p>Vietnamese text-to-speech (TTS) is increasingly evaluated through global intel-ligibility and naturalness measures such as word error rate (WER), F0 error, mean opinion score (MOS), and speaker similarity MOS. These measures do not directly test whether a synthesised syllable preserves its intended lexical tone. This distinction matters because Vietnamese tone is contrastive and multi-c...
