Summary

Text-to-speech (TTS) technology offers a promising way to enhance human-computer interaction by converting written text into spoken words, yet its effectiveness is challenged by the complexity of human speech nuances such as emotion, context, and linguistic correctness. Unlike a simple text-to-audio transformation, TTS systems must navigate the "one-to-many" problem, where a single text can be spoken in numerous ways depending on factors like speaker emotion and pace. Evaluation of TTS models goes beyond basic metrics like Word Error Rate (WER) to include aspects like contextual correctness, naturalness, and robustness, which are not fully captured by automated quality scores. Human evaluations remain the gold standard but are subject to variability based on listener background and presentation details. Long-form and streaming scenarios further complicate evaluations by exposing issues like speaker consistency and streaming artifacts. Additionally, domain-specific texts and multilingual challenges require TTS systems to adapt to specialized vocabularies and pronunciation rules, highlighting the need for evaluations that are tailored to the specific use cases and linguistic contexts of the product.
