VoiceFrequencyTest.com uses a privacy-conscious architecture for its microphone-based tools.
Raw microphone audio is processed locally in your browser or on your device and is not uploaded to our server for audio analysis. However, some derived results generated from that local analysis—such as frequency, pitch, vocal-range, or tone-related values—may be sent to our own server as part of the tool experience.
This page explains that distinction clearly.
How Microphone Processing Works
When you use a microphone-based tool, your browser or device first asks for permission to access the microphone.
If permission is granted:
- your microphone captures the incoming sound
- the browser makes that audio available to the tool
- the tool analyzes the audio locally on your device
- measurable information such as frequency or pitch may be derived from that analysis
- some derived results may then be sent to VoiceFrequencyTest.com’s own server
The raw microphone recording itself is not uploaded to our server for analysis.
For a broader explanation of how the tools generate results, see How It Works.
Raw Audio and Derived Results Are Different
It is important to distinguish between the original microphone signal and the data produced from it.
Raw Microphone Audio
Raw audio is the sound captured through your microphone.
VoiceFrequencyTest.com’s microphone-based tools process this audio locally in the browser or on the device.
The tools do not require your raw microphone audio to be uploaded to our server for server-side voice analysis.
Derived Results
Derived results are values or outputs calculated from the locally processed audio.
Depending on the tool, these may include information such as:
- frequency in Hz
- estimated pitch
- musical-note information
- vocal-range measurements
- tone-related results
- other calculated voice-analysis outputs
These derived results may be sent to VoiceFrequencyTest.com’s own server.
We therefore do not describe all tool-generated data as remaining exclusively on your device.
We Do Not Upload Raw Voice Recordings for Analysis
The normal microphone-analysis workflow does not require VoiceFrequencyTest.com to receive an audio recording of your voice.
Incoming microphone audio may exist transiently in browser memory while the tool performs local analysis, but it is not intentionally uploaded to our server as a voice recording for analysis.
This approach reduces the amount of raw voice data that needs to leave your device while still allowing tools to generate useful results.
Which Tools Use Microphone Access?
Microphone-based tools may include services such as the:
- VoiceFrequencyTest
- Frequency Detector
- Voice Pitch Analyzer
- Vocal Range Test
- Voice Tone Analyzer
- Deep Voice Test
Other tools, such as the Words Per Minute Calculator and Speaking Rate Calculator, may operate from values entered by the user rather than live microphone analysis.
Microphone Permission Is Controlled by Your Browser
VoiceFrequencyTest.com cannot begin using microphone input unless your browser or device allows access.
You may:
- deny microphone permission
- allow permission for a session
- revoke permission later through browser or device settings
The exact interface depends on your browser and operating system.
For general technical information about browser microphone permissions, see the official MDN documentation for getUserMedia().
If permission problems prevent a tool from working, visit Troubleshooting.
Local Processing Does Not Mean the Entire Website Is Offline
Local microphone processing should not be confused with normal website network activity.
Like most websites, VoiceFrequencyTest.com must communicate over the internet to deliver pages, scripts, styles, images, and other site resources.
The important distinction is:
Raw microphone audio is analyzed locally rather than uploaded to our server for voice analysis.
Derived results may be sent to our own server separately from that raw-audio processing.
Our Server and Hosting Provider
VoiceFrequencyTest.com is hosted by Hostinger.
As part of normal website operation, hosting infrastructure may process standard technical information necessary to deliver and secure the website.
This can include information such as:
- IP address
- request time
- requested page or resource
- browser or device information
- server and security logs
- diagnostic information
This type of normal server activity is separate from the local processing of raw microphone audio.
For broader information about personal-data handling, see our Privacy Policy.
Derived Results Sent to Our Server
Some voice-analysis outputs are sent to VoiceFrequencyTest.com’s own server.
Because these results can relate to characteristics of a voice sample, we treat this distinction seriously and avoid implying that all voice-related data remains exclusively on the device.
The exact meaning of an individual result also matters.
For example, a frequency measurement is not the same thing as a raw voice recording, and a numerical pitch value does not by itself reproduce the original audio.
However, voice-related measurements may still deserve careful handling.
Our broader collection, use, and retention practices should be read together with the Privacy Policy and GDPR & CCPA pages.
Google Analytics Is Not Currently Active
VoiceFrequencyTest.com does not currently use Google Analytics.
This means derived voice-tool results are not being sent to Google Analytics through a current Google Analytics implementation.
If analytics technology is introduced in the future, the Privacy Policy and other relevant disclosures should be updated before relying on older statements about the site’s tracking practices.
Advertising Is Not Currently Active
VoiceFrequencyTest.com does not currently use Google AdSense or another advertising system.
There are therefore no current advertising scripts receiving microphone audio through the site’s normal voice-analysis workflow.
If advertising or similar third-party technologies are introduced later, the relevant privacy and cookie disclosures should be updated accordingly.
Third-Party Audio Processing
The microphone-analysis workflow does not require raw audio to be sent to an external audio-processing API.
Raw voice input is analyzed locally on the user’s device rather than being transferred to a third-party service for processing.
This is separate from standard infrastructure providers, such as hosting services, that support normal website delivery.
Browser Storage and Cookies
Browser storage and cookies are separate from microphone audio processing.
Raw microphone audio is not intentionally stored in cookies as part of the analysis workflow.
Some website functionality may use browser-based storage or other technical mechanisms depending on the feature involved.
For current details about cookies and similar technologies, see the Cookie Policy.
HTTPS
VoiceFrequencyTest.com is delivered using HTTPS.
HTTPS helps protect ordinary web traffic in transit between your browser and the website.
This protects normal website communications but should not be confused with the local microphone-processing design itself.
Raw microphone audio used for analysis is not uploaded to our server as part of the normal analysis process.
Why We Minimize Raw Voice Data
Voice recordings can contain personal information and may reveal characteristics about an individual.
For that reason, we prefer an architecture that avoids sending raw microphone recordings to our server when local processing can perform the required analysis.
This reduces unnecessary collection of the original audio while allowing certain derived measurements to be transmitted when needed by the tool.
Security Has Limits
No website, browser, server, device, or internet connection can be described as completely risk-free.
We therefore do not claim:
- that a security incident is impossible
- that every browser behaves identically
- that internet transmission can never fail
- that any technical system provides absolute security
Our goal is to minimize unnecessary data handling, describe the current architecture accurately, and update our disclosures when implementation changes.
Tool Development and Review
VoiceFrequencyTest.com is founded and maintained by Amelia Foster, a PAVA-Recognized Vocologist with a Ph.D. in Speech and Hearing Science and six years of experience working with voice frequency, pitch, and vocal analysis.
Amelia personally builds, develops, and tests the site’s tools.
Part of that work includes reviewing how microphone access, local processing, derived results, tool outputs, and user-facing privacy explanations behave in practice.
You can learn more about Amelia on the Author page and about the site’s publishing standards in the Editorial Guidelines.
