What is Voice Privacy?

Voice privacy refers to technology that protects voice data from unintended access or use. Voice privacy settings allow users to control how their voice data is collected, stored, and utilized by companies. With the proliferation of voice-enabled devices like smartphones, smart speakers, and in-car systems, voice privacy has become increasingly important.

Voice data can reveal sensitive personal information – everything from medical conditions to location history. Without proper voice privacy protections, this data could potentially be accessed, shared, or exploited without the user’s consent. Voice privacy settings give users more control over their privacy. For instance, some settings limit or disable a device’s ability to save voice recordings.

Maintaining voice privacy is crucial as voice assistants and voice-driven tech become ubiquitous. As this article points out, voice data risks being “interrupted, intercepted or recorded without consent.” Proper voice privacy preserves users’ agency and dignity in an age of ambient computing.

How Voice Privacy Settings Work

Voice privacy settings on smartphones function by encrypting voice data and restricting apps’ access to microphones. When voice privacy is enabled, voice data is encrypted before leaving the device so it cannot be intercepted and decoded. This prevents third parties from eavesdropping on calls or accessing voice data.

Technically, voice privacy settings regulate app permissions for the microphone. Users can choose which apps have access to the microphone and when. Disabling microphone access prevents apps from collecting voice data in the background. Voice privacy settings essentially act as a switch, allowing users to toggle microphone access on and off for different apps and purposes.

On Android phones specifically, the voice privacy setting encrypts call audio using 40-bit encryption. This scrambles the voice data through an algorithm that can only be unscrambled with the right cryptographic key. The recipient’s phone also needs 40-bit decryption enabled to unlock the audio. This end-to-end encryption prevents man-in-the-middle attacks and keeps calls private.

In summary, voice privacy settings encrypt voice data and manage app permissions to restrict access to microphones. This gives users control over their voice privacy and prevents unauthorized collection of voice data.

Enabling Voice Privacy

Voice privacy settings can typically be found in your phone’s settings or calling menu. Here are the steps to enable voice privacy on some major platforms:

On iOS devices like iPhones:

  1. Go to Settings > Phone > Calls on Other Devices
  2. Toggle on “Wi-Fi Calling” to enable voice privacy for calls over Wi-Fi

On Android devices:

  1. Open the Phone app and tap the More/Three Dots icon
  2. Go to Settings > Calls
  3. Toggle on “Enhanced voice privacy” or “Voice privacy”

On Samsung Galaxy phones:

  1. Open Phone app and tap More options > Settings > Calls
  2. Enable “Enhanced voice privacy mode”

For Verizon phones, you can enable voice privacy by:

  1. Opening the Phone app and tapping *228
  2. Listen to the voice prompt and press 1 to enable

Consult your phone’s user manual for exact steps. Once enabled, voice privacy encrypts your calls for added security and privacy.

Voice Data Collection Risks

Voice data can reveal a tremendous amount of sensitive information about users, including identity, location, health conditions, age, gender, race, emotions, and more. Voice is a unique biometric identifier, and extensive voice data collection poses significant privacy risks (https://kardome.com/blog-posts/voice-privacy-concerns).

There is concern that collected voice data could be used or accessed for unethical purposes. Voice recordings contain incredibly intimate information, and collection on a mass scale raises fears of profiling, discrimination, exploitation, and surveillance. There is also the danger of voice data being hacked, leaked, or misused by malicious actors (https://abcnews.go.com/Technology/collection-voice-data-profit-raises-privacy-fears/story?id=96363792).

While companies claim to use voice data only for improving services, the lack of transparency and potential monetization of this data is worrisome. Users have little control over or awareness of how their voice data is used after collection. More regulation and user empowerment tools are needed to mitigate privacy risks from extensive voice data gathering.

Voice Privacy Laws and Regulations

There are currently limited government policies regulating the collection of voice data, but several states have enacted laws pertaining to this issue. According to one article, four states – California, Texas, Washington and Illinois – have passed laws related to the collection of voice data.

For example, California’s Anti-Eavesdropping law makes it illegal to record private conversations without consent from all parties involved. Washington’s law requires notification and consent for any recording of private communications. Texas and Illinois also have two-party consent requirements for recording conversations.

At the federal level, there are no comprehensive policies governing voice data collection. However, advocates have been pushing for stronger voice privacy protections. The Voice Privacy Act was introduced in Congress in 2020, but has not yet advanced. This proposed law would require consent before companies could collect, use, or share voice data.

Going forward, privacy experts expect more legislation at both the state and federal levels aimed at regulating the commercial use of voice data and protecting consumer privacy. There is growing concern about the lack of transparency and control over how voice data is being used by tech companies.

Voice Privacy Concerns with Virtual Assistants

Virtual assistants like Siri, Alexa, and Google Assistant have raised privacy concerns due to their always-listening capabilities. These voice assistants continuously listen for their wake word in order to respond on demand. But what happens to the voice data they collect in between commands?

According to the FTC, virtual assistants record and transmit your voice data to their parent companies for analysis and storage [1]. While most claim to only listen for the wake word, privacy advocates argue these devices still pick up private background conversations. There are concerns around how this voice data is used and shared.

In surveys, many smart speaker owners express discomfort with the idea of tech companies having recordings of their private conversations. A study found 40% of users worry about “who is listening” and what happens to their data [2]. Users want more transparency and control over their voice data.

There’s also a fear the always-listening microphones could be hacked. While rare, some incidents have been reported of Alexa devices mysteriously laughing or Google Home recordings being leaked. This raises security concerns in addition to privacy ones.

Protecting Yourself with Voice Privacy Settings

Enabling voice privacy settings can provide certain benefits when it comes to protecting your personal data. According to Google, voice privacy settings “let you control whether Google saves audio from your interactions with Assistant to improve speech recognition technology” (source). With voice privacy enabled, Google claims audio recordings are not associated with your account or used to personalize your experience.

However, there are some limitations to relying solely on voice privacy settings for protection. As noted by Microsoft, “Our new opt-in voice settings allow you to give Microsoft permission to sample and listen to these voice clips to improve our speech recognition technology” (source). So even with voice privacy on, snippets of recordings may still be used, just not associated with your identity.

Additionally, voice privacy settings do not prevent microphone access or recording capabilities on your devices. They simply limit the association and usage of those recordings. For full protection, users may want to research additional privacy measures beyond just voice privacy settings.

Voice Privacy Settings on Major Platforms

Major mobile platforms like iOS and Android allow users to control voice privacy settings. Here’s how to find and manage them:


On iOS devices like the iPhone, you can limit app access to voice data through the Voice Control settings. Go to Settings > Accessibility > Voice Control and toggle off “Allow Siri & Voice Control Access” to disable access to voice input across apps (https://support.apple.com/guide/iphone/use-voice-control-iph2c21a3c88/ios).

You can also create a Personal Voice profile thatencrypts your voice so it can’t be used to identify you. This is configured in Settings > Accessibility > Personal Voice (https://support.apple.com/en-us/104993).


On Android phones, voice privacy settings can be managed through the Google app. Go to Settings > Google > Account services > Voice & Audio Activity. Here you can pause voice and audio recording by Google services.

Some Android phones may also have toggles to disable microphone access for specific apps in the app permissions settings.

Other Platforms

Most mobile and desktop platforms have some form of voice privacy controls in the system settings. It’s a good idea to review the privacy options to find voice-specific toggles.

Voice Privacy Outlook

As voice assistants and biometric authentication become more prevalent, there are ongoing debates around voice data collection and privacy. According to Insider Intelligence [1], there will be 145.1 million voice assistant users in the US by the end of 2023. While voice assistants provide convenience, some critics argue companies could use voice data for unauthorized purposes.

Looking ahead, we may see tighter regulations around voice data usage and transparency. In 2019, some US senators introduced a bill called the Consent Act to require companies to obtain consent before using voice data. The EU’s GDPR also provides a framework for voice privacy protections [2]. Many experts predict growth in on-device processing, which allows voice commands without transmitting data to the cloud.

There are also emerging technologies like acoustic fingerprints and voice masking that aim to improve voice privacy. Overall, expect ongoing debate as voice assistant adoption increases. Companies will need to be more transparent in how they use and protect sensitive voice data.


Protecting your privacy when using voice-enabled services is important. Voice data can provide insights into your habits, interests, and daily patterns. While there are benefits to companies collecting this data, users should be aware of the risks and enable voice privacy settings if they wish.

The major platforms like iOS, Android, Amazon Alexa, and Google Assistant all have settings to limit voice data collection. Take time to review these settings and choose the options that align with your privacy preferences. Be aware that full voice privacy may disable some features.

Going forward, voice privacy will likely remain an issue as more devices integrate voice services. Make sure to stay updated on privacy policies, new products, and any regulations that emerge around data practices. Although we can’t control everything companies do with voice data, enabling privacy settings is an important step towards managing our digital footprints.
