I built VoiceFlow while preparing a talk for a local startup event. I recorded myself and couldn't get past 20 seconds without cringing at how many times I said "o sea" and "literalmente." Speech coaches in Madrid charge €80–150/hour. The apps I found either required a subscription, only worked on desktop, or gave feedback so generic it was useless. So I built the thing I wanted: open browser, hit record, get honest numbers. No account, no paywall. Three months of daily 5-minute sessions later, my filler rate went from 11 to 2 per minute. Zero email required. Open voiceflow.es in any browser and start practicing
