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

Amazon Halo Tone analysis feature

Amazon Halo is probably the only leading wearable in the market that offers 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 spend listening, the tone of our voice becomes an important attribute in how we are perceived by others.

More importantly, your tone can provide insights into your overall 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.

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, your children, or your work colleagues can help strengthen the relationships.

Although there has been a lot written out there about potential privacy issues with Amazon Halo when it comes to 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 Halo provides around privacy.

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

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

Nobody can listen to your conversations ( for 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 you are 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. Gives some peace of mind knowing that personal voice information is not shared with third-party entities. Check the Amazon Halo Privacy policy for more details.

Optimize Halo Battery performance when using 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 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 are at least able to use the band for 2 days between charges. 



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

We tried out low pitch and high pitch voices, 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. As you are speaking, you can see the tone analysis play out on the app.

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

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

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

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