In football, we measure almost everything.
Except what coaches say.
What clubs already measure
- Physical performance
- Tactical behaviour
- Technical development
- Match statistics
- Medical data
Make coaching communication visible.

Even the best people responsible for coach development and support cannot observe every interaction.
The limitation is not expertise.
The limitation is scale.
Which means it is hard to systematically:
- observe the communication of every coach
- recognise patterns and changes over time
- track how the shared development philosophy is put into practice

Seeing every session and match would take several full-time staff doing nothing but observation.
Sessions run in parallel. No one can be in two places at once.
Coaching analysis and feedback
Every session and match can come back to the coach as development material.

How it works
01Record the session
Capture the training with any headset, lavalier mic or phone. No dedicated hardware needed.
02Upload the recording
Upload the audio file to the Sfera0 Voice platform in a few clicks.
03Coach's voice only
The platform automatically separates the coach's voice from other coaches and players. Players' voices are not processed.
04Transcription
Only the coach's voice is transcribed into text, ready for analysis.
05Sfera0 Voice Analyze
A full analysis of coaching communication: SDT, coaching style, football domains and more.
06Full report
A complete coach report is ready in about 20 minutes.
Behind every number
are the coach's words.
Percentages show how the coach's communication is distributed. They are not a rating of the coach.
Each percentage in Sfera0 Voice is calculated from the coach's own utterances. Behind every number are the exact moments from the session, with timestamps.
Real quotes, not estimates
Every percentage links to transcript evidence.
Timestamped
Jump to the moment in the session it happened.
Explained
Each utterance is labelled and described, so coaches know why it counts.
Numbers show the pattern. Real quotes make feedback concrete.

Transcript excerpt
See the bigger picture of coaching.
Track communication patterns across teams, identify strengths and development opportunities, and see how coaching evolves across your club.
Every communication insight is supported by evidence from real coaching conversations.
One platform. Every level of the game.
Feedback and support on demand. When the coach asks for it.
Coaches ask in their own words. The Assistant answers using only what they said in their own sessions, with the minute and the quote, grounded in sport science.
On the coach's request
Nothing is pushed. The coach decides when to ask and what about.
Answers from the coach's own sessions
Specific to how they actually coach, with the minute and the exact quote. Never generic advice.
Grounded in sport science
Answers follow SDT and coaching-style research, the same frameworks as the report.
How can I support autonomy more?
- Reading your session
- Analyzing your session
- Finding your examples
You're already on the right track. Remember when you asked:
“How would you play it? Show me.”
That hands the choice to the player. Ask it more often.
Communication Intelligence is becoming football's next competitive advantage.
Clubs that understand how their coaches communicate develop players faster and keep their philosophy consistent.
Scale expertise
Multiply the impact of your coach developers and psychologists, without adding staff.
Protect development investments
Get more from every euro invested in coaching, psychology and performance.
Accelerate coach development
Less time between feedback and action.
One communication culture
Every player experiences the same development philosophy, in every team.
An organisational knowledge asset
Searchable, measurable knowledge that stays inside the club.
The clubs that learn faster will outperform the rest.
Communication Intelligence helps clubs learn from every coaching interaction, not just the ones someone happened to see.
Built to protect the decisions, data and people behind the game.
