Taking the Voice Biomarker Test

Learn how to perform a voice analysis test to record acoustic characteristics of your voice.

This test records acoustic patterns in your voice including frequency, amplitude, and timing characteristics.

⚠️ Preview Feature — Coming Soon

Voice Analysis is available in the app but the biomarker analysis engine is in preview. Results may be limited or inconsistent while we tune the models. Some specific score outputs described below may not yet be visible on your device.

Before You Start

For Best Results

Environment:

  • Find a quiet place to minimize background noise
  • Close windows to reduce external sounds
  • Turn off fans, TV, or music
  • Notify others you need quiet for 15-30 seconds

Phone Position:

  • Hold your phone about 6-12 inches from your mouth
  • Keep it steady throughout the recording
  • Speak toward the microphone (usually at the bottom)
  • Avoid covering the microphone with your hand

Preparation:

  • Be prepared to speak for at least 10-15 seconds
  • Clear your throat beforehand if needed
  • Have a glass of water nearby
  • Be in a comfortable, relaxed state

Accessing the Test

Step 1: Navigate to the Home tab

Step 2: Scroll down to find the Health Tests section

Step 3: Tap on the "Voice Analysis" card

Step 4: Read the instructions on the screen

Performing the Test

The test involves two parts that you'll perform consecutively:

Part 1: Sustained Vowel Sound

What to do: Say "Ahhhh" in a steady, comfortable tone

Duration: About 5 seconds

Tips:

  • Use your natural speaking pitch
  • Don't strain or force the sound
  • Keep the tone steady and consistent
  • Breathe deeply before starting

Part 2: Natural Speech

What to do: Continue by speaking naturally about your day

Tips:

  • Speak in your normal conversational voice
  • Don't read or recite memorized text
  • Use natural pacing and rhythm
  • Be authentic and relaxed

Recording Your Voice

Step 1: Tap the microphone button (🎤) at the bottom of the screen to start recording

Step 2: The button will turn into a stop icon, indicating recording is active

Step 3: Perform both voice tasks:

  1. Start with "Ahhhh" for 5 seconds
  2. Transition smoothly to natural speech for 5-10 seconds

Step 4: Tap the stop button (⏹️) when you are finished

After Recording

Processing Your Sample

Once you stop recording:

  • The app will automatically upload your voice sample
  • Analysis begins immediately
  • This may take 10-30 seconds
  • You'll see a progress indicator

What's Being Analyzed

The system examines acoustic features including:

  • Pitch and frequency characteristics
  • Voice stability measurements
  • Speech timing patterns
  • Harmonic patterns
  • Frequency distributions
  • Amplitude variations

Tips for Optimal Results

Voice Condition

Best conditions:

  • Well-hydrated (drink water before testing)
  • Rested voice (not after long conversations)
  • Normal health (not during illness)
  • Relaxed throat and vocal cords

Avoid testing when:

  • You have a cold or sore throat
  • Voice is hoarse from shouting
  • Immediately after waking up
  • Very stressed or emotional

Technical Quality

Phone placement:

  • Consistent distance from mouth (6-12 inches)

  • Hold steady or use a stand
  • Don't tap screen while recording

Audio quality:

  • Ensure microphone isn't blocked
  • Clean microphone if dusty
  • Check volume isn't too low
  • Avoid wind or fan noise

Speaking Technique

For sustained sound (Ahhhh):

  • Start at comfortable volume
  • Maintain steady pitch
  • Don't crescendo or diminish
  • Breathe deeply before starting
  • Relax jaw and throat

For natural speech:

  • Use conversational tone
  • Speak at normal pace
  • Don't whisper or shout
  • Be expressive and natural
  • Complete full sentences

Common Issues & Solutions

"Background Noise Too High"

Solution:

  • Move to a quieter location
  • Close windows and doors
  • Turn off air conditioning/heating
  • Wait for external noise to pass

"Recording Too Short"

Solution:

  • Ensure you speak for at least 10 seconds total
  • Don't rush through the test
  • Hold the sustained sound longer
  • Add more natural speech

"Poor Audio Quality"

Solution:

  • Clean your phone's microphone
  • Move closer to the phone (but not too close)
  • Speak louder (but still naturally)
  • Check microphone permissions are granted

"Voice Not Detected"

Solution:

  • Speak directly toward the microphone
  • Increase volume slightly
  • Ensure microphone isn't covered
  • Check app permissions in Settings

When to Test

Best Times

Daily baseline: Morning after waking and having water

Before/after events: Track changes around stressful periods or illness

Regular intervals: Weekly or bi-weekly for trend tracking

When feeling different: Notice vocal changes or emotional shifts

Testing Frequency

Minimum: Once per week for baseline tracking

Optimal: 2-3 times per week for pattern recognition

Maximum: Daily if monitoring specific condition

Privacy & Data

Your Voice Recording

Storage:

  • Recordings are processed and then deleted
  • Only analysis results are saved
  • Raw audio is not permanently stored
  • Data is encrypted during transmission

Usage:

  • Used solely for your health analysis
  • Not shared with third parties
  • Not used for voice identification
  • You control all data through the app

🎤 Pro Tip

Test at the same time of day and in the same location for most consistent results. Your voice naturally changes throughout the day, so maintaining consistency helps identify meaningful changes.
