Amazon Halo Tone Analysis : A Beginner’s User Guide and review

Amazon Halo Tone analysis feature

Amazon Halo is probably the only leading market wearable offering the tone analysis feature. Did you know that many of us spend 70 to 80 percent of our waking hours in some form of communication?

Of that time, we spend about 9 percent writing, 16 percent reading, 30 percent speaking, and 45 percent listening.

Since so much time is spent listening, the tone of our voice becomes an essential attribute in how others perceive us.

More importantly, your tone can provide insights into your mental and emotional state. It has been proved in numerous studies that psychological stress can affect your emotional prosody.

This is where the first iteration of Amazon Halo’s tone analysis feature comes in.

Read on to understand how this feature works, how it can be set up, data and privacy-related mitigations, and tips to optimize the battery performance when using this feature.

UPDATE: Amazon no longer supports Halo products, including the Halo Band, Halo View, and Halo Rise. Beginning on August 1, 2023, these products and the Amazon Halo app won’t work.

What is the Amazon Halo Tone analysis feature?

Amazon defines the ‘Tone’ feature on their Halo band as a tool that you can use to

“Analyze the qualities of your voice like energy and positivity to help strengthen communication.”

Knowing how you sound to others, whether your spouse, children, or work colleagues, can help strengthen relationships.

This feature is available on the Amazon Halo Band (no display) and the Amazon Halo View (small color display) via the Halo smartphone app. 

The Tone feature uses the smartphone’s microphone to analyze the tone of voice used during conversations.

How does the Halo Fitness Tracker Tone analysis work?

Amazon Halo Tone Analysis user guide and reviewAmazon’s Halo fitness tracker has a built-in microphone that captures your voice. Please note that the device captures ONLY YOUR VOICE during any conversations.

When Tone analysis is enabled on your Halo band, the microphone captures your voice as you speak with others.

Amazon’s tone analysis algorithms then process your voice on their servers, and you are presented with results that give you a glimpse of how others might perceive you from the tone of your voice.

Brief Voice Snapshots

You can set up your Halo Fitness tracker to take brief voice snapshots to understand how your tone varies throughout the day.

Are you more positive in the morning? Is your tone more appealing after a cup of caffeine?

The voice snapshots feature can give you a sense of the trends and help you see patterns.

Bookmark and analyze Important conversations

The other way to use the Tone analysis is to use it more as a tool to bookmark and analyze essential conversations.

Let’s say you are going to be talking to your boss about a potential pay raise. You may want to see how your tone was potentially perceived during that conversation.

You can use the band button to bookmark the entire conversation.

Although there has been a lot written out about potential privacy issues with Amazon Halo regarding tone analysis or even body fat analysis features, we think that some of these issues may be a little overblown, given the amount of control that Amazon has Halo provides around privacy.

We also address some of these controls in this beginner’s guide to Tone Analysis.

The report gives you a percentage split among these four major emotional states to show how your tone was perceived.Halo Tone analysis and Notable moments feature

The report also has a ‘Notable Moments’ section. This section described some moments when you were highly positive or negative.

Typically this section shows ‘Nothing Unusual to report’ most of the time unless it reads a spike in a particular emotion.

How to use Amazon Halo lab tools to improve Tone?

The Lab feature on the Amazon Halo app is an excellent repository of information and tools to help you with various improvements you want.

Numerous lab programs are available to help you improve.

Start by tapping on the Labs tab (the third tab at the bottom from the left).

How to stop or pause Tone Analysis on Amazon Halo tracker

To pause the Tone feature, press and hold the button on the Halo band for 3 – 4 seconds.

This pauses the feature and also mutes the Mic. When you press the button on the halo band, look for the LED light to turn Red, indicating that the Mic has been muted.

Where are Amazon Halo Tone samples stored? How is Privacy handled?

In the case of the Tone feature, the tone samples are processed on your mobile device itself and not moved to the cloud.

When you delete the conversation samples, they are removed from your mobile device automatically.

Nobody can listen to your conversations (e.g., Amazon employees). All the Tone data is stored between your band and your Amazon Halo app on your mobile device.

Nevertheless, all data movement between your band and their cloud servers is encrypted, according to Amazon. 

Please note that when using third-party Labs in various areas, your information is not shared with the third party.

This is helpful if you are using Tone related labs to improve certain aspects of your voice pitch et al.

Knowing that personal voice information is not shared with third-party entities gives some peace of mind. Check the Amazon Halo Privacy policy for more details.

Optimize Halo Battery performance when using the Tone feature

Since the Tone feature uses the microphone to capture voice, it draws a lot more battery.

The amazon Halo band typically gives you  5 – 7 days between full charges, but this shortens dramatically, sometimes just a day, when you use the Tone feature on your fitness band.

If you plan on using Tone, there is a setting that allows you to choose from Less/More Tone recordings. You can access this setting on the Halo app. Open the Halo app on your mobile device.Optimize Amazon Halo battery when using Tone feature

  • Select the Settings tab ( the last tab at the bottom of the screen)
  • Under App Settings, select Tone
  • Choose between Less Tone or More Tone here to optimize battery usage

Recommend using it with the ‘Less Tone’ setting so that you can use the band for two days between charges. 



We tried Halo’s Tone analysis feature and were pleasantly surprised by it. The real-time analysis of your tone works remarkably well when identifying the emotion behind the voice.

We tried out low-pitch, high-pitch voices, and soft tones, and the reception on the Amazon Halo’s microphone was spot on.

There is hardly any latency when using this feature combined with the Halo app. The tone analysis plays out on the app as you speak.

The ability to go back and introspect on a bookmarked conversation was also a very eye-opening exercise.

Concerning privacy, it was comforting to know that the app stores only your voice. When you set up Amazon Halo’s Tone analysis feature, you first set up a Voice profile id.

Any sounds matching that Voice profile are only captured for analysis. Deleting all the bookmarked conversations from the device was also very easy.

All in all, it was a reflective experience trying out Halo’s tone analysis. It is hard to imagine how much power has been packed into a $70 Fitness band!

There’s also a less expensive Halo that comes with a small color screen.

The Amazon Halo band has been discounted from its original price and is now available directly from Amazon.
