What Is Speech Analysis?

Speech analysis is the process of turning spoken audio into measurable data — how fast you speak, how often you use filler words, how clear your phrasing is, and how confident you sound. Speech analytics software does this automatically so you can improve how you communicate with objective feedback instead of guesswork.

How Speech Analysis Works

It starts with audio. Speech-to-text transcription converts it into words, and speaker diarization labels who said what. Then the software measures delivery: filler-word rate (fillers ÷ total words × 100 — for example, 34 in 1,420 words is 2.39%), speaking pace in words per minute (roughly 120–160 WPM is comfortable), clarity, and grammar.

Speech Analysis vs Speech Recognition

Speech recognition converts audio into text. Speech analysis goes further — it evaluates how you spoke (fillers, pace, clarity, confidence) and returns feedback, pointing to the exact moments you rushed, hedged, or lost the thread.
