Smart Speakers

Smart speakers have built-in intelligent virtual assistants to listen to your commands and respond using artificial intelligence.

What is a Smart Speaker?

Smart speakers are speakers with built-in intelligent virtual assistants. These smart speakers have built-in microphones to listen to your commands and respond using artificial intelligence.

Users can communicate with the smart speaker by giving voice commands, such as asking questions or commanding them to do a task, such as playing music, adding items to shopping lists and setting reminders and alarms. 

Amazon’s smart speakers are a prime example with a built-in virtual assistant called “Alexa”, which generally responds to questions like “What is the temperature outside now?” or “What are the best-selling earbuds?” for which it searches the internet to find the answer and reads them out. 

How does a smart speaker work?

Smart speakers use hardware and software components to process voice commands, connect to the internet, and interact with various smart devices. 

Here’s a breakdown of how they generally function:

Microphones – Smart speakers use built-in microphones to listen to noise from their surroundings constantly. Most modern smart speakers have more than one microphone to increase the ability to catch anything you say. For example, the Amazon Alexa Echo Dot has six microphones. They also rely on activation phrases such as “Alexa,” “Hey Google,” or “Hey Siri”, which, when they detect, begin recording the user’s voice command.

Speech Recognition – The recorded voice command is processed by the speaker’s speech recognition software, which converts the spoken words into text using sophisticated algorithms. This text data is then analysed using clever algorithms to understand the user’s intent and extract the meaning behind the command.

Connection to cloud – The interpreted command is sent over the internet to cloud-based servers.  These servers process the request, access vast information databases, and perform the requested tasks.

Task execution – The smart speaker’s cloud-based service performs the necessary actions based on the interpreted command. This could involve retrieving information like weather updates or news, controlling smart home devices, setting reminders, playing music, making purchases, and more.

Feedback and Response – Once the action is completed, the smart speaker may respond verbally or perform the requested task, such as turning off lights, playing a specific song, or providing the requested information.

Integration with smart home devices – Smart speakers communicate with various smart devices, lights, thermostats and cameras using compatible protocols like Wi-Fi, Bluetooth, Zigbee, or Z-Wave. They act as a central hub to send commands to these devices, enabling users to control their smart homes via voice commands.

The continuous advancements in artificial intelligence, machine learning, and improvements in hardware components contribute to the enhanced capabilities and responsiveness of smart home speakers.

Smart speakers, Bluetooth speakers & Wi-Fi speakers:

What is the difference between Smart speakers, Bluetooth speakers & Wi-Fi speakers?

Although they are all speakers, Smart, Bluetooth, and Wi-Fi speakers serve different purposes and have distinct functionalities. 

Smart speakers are multifunctional devices with voice assistants and various innovative capabilities beyond just playing music. In contrast, Bluetooth and Wi-Fi speakers focus primarily on wireless audio playback but have different connectivity and functionality features.

Smart Speakers

Smart speakers have voice assistants such as Amazon Alexa, Google Assistant, or Apple Siri, which are designed to play music, respond to voice commands, and perform various tasks.

They typically connect to the internet via Wi-Fi and have multiple microphones to listen for wake words and process voice commands. They can control smart home devices, provide information, set reminders, play music, and perform various tasks beyond audio playback.

Top Smart Speaker

Amazon Echo – The Echo line offers a range of options with different sizes, capabilities, and price points, all featuring Alexa as the voice assistant.

Smart speaker and Smart display:

What is the difference between a Smart speaker and a Smart display? The primary difference between a smart speaker and a Smart display lies in their form and functionality:

Smart SpeakerSmart display
A smart speaker is primarily an audio-focused device. It typically resembles a traditional speaker and is designed to produce sound.An intelligent display integrates a screen and a smart speaker’s functionalities. It resembles a tablet or digital picture frame with an attached speaker.
Smart speakers have microphones and built-in voice assistants (like Alexa, Google Assistant, or Siri). They can respond to voice commands, answer questions, play music, control smart home devices, set reminders, and perform various tasks solely through voice interaction.In addition to the capabilities of a smart speaker, intelligent displays offer a visual interface. They can show information such as weather forecasts, cooking recipes with step-by-step instructions, calendar events, video calls, and visual responses to queries.
Smart speakers lack a screen or visual interface, unlike smart displays. They rely entirely on audio feedback for interactions.Smart displays are handy when visual information complements voice interaction, such as following recipes, viewing weather forecasts, watching videos, or making calls.

In essence, while smart speakers and smart displays share similar voice assistant capabilities, smart displays add a visual component through an integrated screen, offering a more interactive and visually enhanced user experience than smart speakers.
