Setting the Benchmark in AI Voice API

99.38% Pronunciation Accuracy

We evaluated our system’s pronunciation using real-world language data from the Leipzig Corpus. From 300,000 multilingual news sentences, we selected 4,710 test words, and had anonymous native speakers review each word twice. Testing across six languages, our system achieved 99.38% accuracy.

emotii Wins 8/10 Times on Voice Naturalness

Trained on 70,000+ hours of diverse speech data, Murf’s voices are indistinguishable from human speech. In a blind test across four English locales and 8 other languages, anonymous native speakers evaluated 11,000+ audio sample pairs using style-appropriate scripts. 8 out of 10 times, Murf voices won on naturalness in comparison to leading competitors. This 8/10 win rate reflects Murf’s success across all competitor tested languages, winning in 34 out of 42 language comparisons, which equals ~80%.
