AI voice assistants are sophisticated software programs that use artificial intelligence to interpret human speech and respond via synthesized voices, leveraging technologies like natural language processing and machine learning to understand and execute voice commands. As reported by Bloomberg, these assistants are becoming increasingly advanced, with companies like Apple developing new features such as infrared cameras to enhance spatial audio experiences and improve integration with emerging technologies.

What Are AI Voice Assistants?

When you ask Siri to search for something online or tell Alexa to play a song, you're already talking to AI voice assistants. These smart, AI-powered software programs can comprehend your spoken commands and even respond to them in seconds.

They are everywhere nowadays: in your phone, in your work equipment, and even in your appliances. From setting reminders to controlling smart home devices, you can rely on them to do your bidding.

They're very accessible because using them is completely hands-free, which is pretty useful when you're busy and have your hands full. All you have to do is talk to your voice assistant and it will listen to you, process your requests, perform the task you've given, and notify you once everything is done.

You won't have to type out lengthy, detailed prompts or fiddle with your device until it agrees to execute your orders. With many gadgets and equipment getting AI integrations, a voice assistant completes the package in terms of convenience and functionality.

How AI Voice Assistants Work: The Mechanisms That Run Them

developer.nvidia.com

Speech Recognition: AI can't act on your commands if it doesn't hear you. This is why it needs to be able to identify when someone is speaking and convert those spoken words into text that the algorithms can process. This is called Automatic Speech Recognition (ASR) technology

. It soaks in your voice through the device's microphone, which it transmits as analog signals and turns into digital signals that are processed using acoustic modeling. Acoustic modeling picks out phonemes, the distinct units of speech sound, and then language modeling weaves these sounds together to form words and sentences

. Some ASR systems can even precisely identify accents and languages by using deep neural networks for mapping audio features to phonemes or sub-word units

. Natural Language Processing: Even if the voice commands are already converted into text, the system still needs to deduce their purpose and meaning before it can comply. This is where Natural Language Processing (NLP) algorithms take over

. They scan the text, making sense of the words, recognizing their nature, and piecing them all together like puzzle pieces that fit to form a new meaning. After they know which ones are nouns, verbs, and modifiers, they will semantically analyze them as a whole to grasp definitions and the full context. Since machine learning models are trained on vast amounts of text data, they assist in this stage to surmise intent and the distinctions of human language

. Response Generation: Once the AI has completely understood its task, it will do as it was told and give its answer. Before this, though, it would have to perform several steps so it can deliver what's asked of it. It gathers related information from its knowledge base or connected services, which it will forward to natural language generation (NLG) algorithms for constructing a coherent and relevant response

. This may involve summarizing information, formatting data into easily understandable sentences, or generating follow-up questions if more details are required. The text reply is then spoken aloud through Text-to-Speech (TTS) technology

. If you want your voice assistant to sound a certain way, some devices let you adjust the voice modulation and tone in the settings.
