UnverifiedWER (word error rate) measures the difference between ASR transcription and reference text, and MOS (mean opinion score) measures the naturalness of synthesized speech; these were the two core metrics for speech evaluation in the past.78% similarUnverifiedIn speech synthesis, the evaluation standard for quantization quality is generally comparison with the output of the original FP16 model, commonly measured using similarity metrics and subjective audio naturalness ratings (such as MOS).73% similarUnverifiedThe chaining of three layers of capability—speech recognition (ASR), natural language understanding (NLU), and scheduling planning—determines whether voice commands can be executed accurately, and an error in any layer leads to misoperation.70% similarUnverifiedThe core dimensions for evaluating TTS quality include voice naturalness, emotional expressiveness, multilingual and multi-accent support, and whether SSML markup is supported to control speed, pauses, and stress.69% similar
