The evolution in technology manages to astound us with every passing day. How many of us would have considered the possibility of purchasing products that could speak a few years ago? However, products equipped with voice capabilities are now a reality.
In the coming years, there would be even more products and devices which would be equipped with microphones and would have the ability to speak. You must have noticed the popularity, that devices like HomePod and Echo have managed to acquire. Within a few years, even more, such products will be introduced in the market.
Companies are now contemplating incorporating AI in more of their devices to provide the users with a different experience.
Is it the right choice?
This is the question that many brands are asking themselves. Those who have not ventured into the world of voice interaction cannot help but wonder if this capability should now form part of their products.
The primary concern that they have is whether this popularity of voice interaction is just a trend which would fade away with time or is actually here to stay. Will this technology prove to be profitable in the long run? Would it manage to give a boost to your business?
Considering all the possibilities is essential. How much of an impact do you expect the technology to make? Voice capability is not just something that can give users an enhanced experience and convenience. Manufacturers can also use it to make things easier in quite a few ways as well.
For instance, this technology can be used to gather analytics on environments. You can use it to detect sound events. It might even be possible to unify multiple AI assistants.
These days, when we think about voice interaction, it is standalone products like the Echo that come to mind. However, that has started to change. The voice is now being embedded into a diverse range of products.
Indeed, announcements have been made with regard to voice interaction in various products including fans, light switches, thermostats, and electronics among other things. Measures are also being taken to integrate voice in everyday appliances like fridge, alarm clocks, and washing machines.
If implantation of voice and related technology is given some thought, the makers have the opportunity to apply it in various ways.
The technology is pivotal in controlling devices. The devices can follow simple commands like that of a turn-off and on or changing the volume. It might not even be necessary for the device to be connected to the internet for this interaction. Dedicated hardware with power mode might make things work.
The option is also available to integrate with AI assistant. If this is put into practice, the end-to-end voice assistant might become feasible.
The technology can be used to sense the environment or gather analytics. It is not merely voice commands that microphones can capture. They might also be able to identify environmental sounds. They can also be used for the measurement of sound level. Rules can be created around volume as well.
Thus, there are four main areas where voice interaction can excel. These include:
- Far-field digital signal processing
- Local speech recognition
- APIs with new speech recognition
- Microphone technology
Local speech recognition
Local speech recognition can go a long way. It can be used to initiate voice recognition based on a specific command. It might also play a role in the initiation of vocabulary interaction on a larger scale.
Work is in progress in this area by quite a lot of companies. Many have even released their advancement in technology to the market.
Digital signal processing
This is one of those areas where immense progress has been made. Digital signal processing is integral for processing audio so that voice can be picked up from a distance and the ambiance noise is cancelled out. It also plays a role in the separation of voice signal such that speech recognition becomes feasible.
With this, the ability of the device to hear your command and respond accordingly even in noisy settings becomes a possibility.
Chips of DSP have become less expensive with a period of time, and the cost is expected to lower down further in the coming years.
One factor that needs to be considered about companies contemplating to add voice is that if the low cost in this technology is likely to become lower in the near future. Perhaps in time, the code might be available free of charge.
However, if a free solution is acquired, flexibility might be limited, and thus the application of the technology would suffer.
Some points to consider
New services for the technology are now gaining prominence. For instance, in the case of Google assistant and Alexa, while both get the service free of cost, an increase in accuracy is also witnessed.
With low cost and increased accuracy, companies are likely to be more attracted to incorporate voice to hardware. Mic with this latest technology is also now available at a lower cost while at the same time; there has been an improvement in their inbuilt processing ability.
However, some probable drawbacks have to be paid heed to as well. The increase in material costs, the security risks and the likely decrease in brand power are some of the factors that have to be considered.
Once you include voice interpretation in a line of products, you become bound to incorporate this technology in the subsequent products introduced in the line as well. This will have an impact on certification and tooling as well.
Legal implications of adding voice also have to be considered. If measures are not taken for the prevention of hacking, the company can be at high risk. Therefore, it is essential that physical mute buttons are added and there is an indicator to let one know that the listening device is one to ensure that no tampering occurs.
It is also vital that the information the device sends is subjected to encryption. Steps for authentication need to be taken to ensure that hijacking into devices is not possible.
It is also important to consider how adding the feature of voice impacts the brand. For companies who do not have the means of including their own voice assistance have to think about the implication of users referring to their product as Alexa. This might lead to the erosion of their brand power.
However, if a company does add voice feature, there are quite a few doors of opportunities that will open for them as well.
The technology enhances the ability of a device to pass on a particular session to another device. Think of a possibility wherein you indulge in a conversation with Alexa on some device, only to continue it on another as you go about your business. This will only be a possibility if multiple devices use the same integration.
In the case of microphones, it might become easier to acquire an understanding of the users interact with a piece of hardware. There are quite a few questions that warrant attention. For instance, is the device actively being used? How often do the users put the device to use? What requests do these users have for the device?
Voice interaction provides a way via which more can be determined about these requests thereby enabling further engagement with the end-users.
To erase the confusion
If you are on the fence regarding adding voice, it would be a good idea to view this feature as other features out there like control interfaces and touch among other things.
The feature aims to provide users with optimal convenience. Furthermore, it also can be used to open the silos of AI assistance as it unifies them via a single device. New users can be won over by this feature.
