Capture Every Dimension of Candidate Speech
Go beyond answers. Twirln's Speech Analysis captures communication clarity, confidence, fluency, sentiment, grammar, and pace — giving recruiters the complete picture.
6 Key Speech Metrics We Capture
Every candidate interview is analyzed across six critical dimensions of spoken communication
Communication Clarity
Measures how clearly candidates articulate ideas, structure responses, and convey complex information effectively.
Confidence Level
Evaluates vocal assertiveness, tone stability, and the candidate's composure throughout the interview.
Fluency & Flow
Tracks speech continuity, filler word frequency (um, uh, like), pauses, and overall delivery smoothness.
Sentiment & Tone
Analyzes emotional tone — positive, neutral, or negative — and detects enthusiasm, hesitation, or discomfort.
Grammar & Vocabulary
Assesses grammatical accuracy, vocabulary richness, and professional language usage in spoken responses.
Pace & Timing
Monitors speaking speed (words per minute), response time, and whether answers stay within optimal length.
