BioSpeech
BioSpeech connects Speech Companion with Apple Watch heart rate data so speakers can see how physiological stress affects vocal delivery, pacing, and confidence during real practice conditions. BioSpeech is based on research conducted by Dr. Dennis Becker, Paula Borkum Becker, and the team at The Speech Improvement Company, drawing on six decades of applied communication science since 1964.
What BioSpeech Does
BioSpeech captures heart rate trends throughout a speaking session and aligns them with the timeline of your transcript or recording playback. This helps users identify specific moments where anxiety increases, then train targeted breathing, pacing, and structure techniques to reduce stress response.
The connection between physiological arousal and speaking performance has been a core research area for TSIC since the firm's founding. Based on working with over one million professionals over six decades, the TSIC team identified that measurable biofeedback accelerates the coaching cycle and gives speakers objective evidence of improvement that subjective self-assessment alone cannot provide. BioSpeech translates that research into a practical tool available on every practice session. For more on TSIC's immersive approach to biometric speaking research, see speechimprovement.com/vr.

Tips for Better Results
Use Comparable Sessions
Keep duration, topic, and environment consistent when comparing trends over time.
Measure Recovery, Not Just Peak
A faster return to baseline after challenging moments is a critical indicator of speaking resilience.
Combine with Delivery Notes
Tag sections where confidence dropped and map those moments to transcript language and structure.
