4
+ ## Metrics
5
+
6
+ - **RTF - Real Time Factor** - real time factor, how many seconds it takes to create 1 second of audio - (*lower is
7
+ better*)
8
+ - **WER - Word Error Rate** - this is a proxy for understandability, assuming more understandable speech scores better
9
+ in STT, correlates to how many words the TTS pronounces wrong - (*lower is better*)
10
+ - **DAMERAU LEVENSHTEIN SIMILARITY** - this is also a proxy for understandability, assuming more understandable speech
11
+ scores better - (*higher is better*)
12
+ - **Pitch Variability** - Measures the variation in the pitch of the speech. Higher variability can indicate more
13
+ natural, human-like speech, while low variability may suggest robotic or monotone output. (*Higher is better*)
14
+
15
+ > **NOTE**: for STT google is used, and in case of failure Whisper large V3 as fallback
