Building a gateway between you and your voice products with accurate and customized wake words and enhancing the word detection capabilities of voice assistants to help you stay ahead of the competition.

Voice assistants have dramatically transformed the way customers interact with their devices. They have made it easier for users to explore products and services – quickly and efficiently. However, is the voice application listening? To put these applications in high drive, they need to be woken up and transition from passive to active listening with the help of WAKE WORDS. ‘Alexa’ and “Hey Siri’ are two of the most popular wake words in the world.


By 2024, the number of digital voice assistants is predicted to reach 8.4 billion units – more than the world’s population. 

Markets & Markets

The voice assistant app market size is predicted to increase from $2.8 billion in 2021 to $11.2 billion in 2026, at a CAGR of 32.4%. 

What is a Wake Word and, its Examples 

A wake word is a specific word or phrase such as ‘Hey Siri’, ‘Okay Google’, and ‘Alexa’; designed to activate a voice-activated device to respond when uttered. However, an always-listening wake word that is locally integrated with the device reduces the response time drastically and increases the identification and processing accuracy of the wake word even without an internet connection.

How Shaip can help?

With Shaip’s offers always-listening wake word training, your voice assistant models are always tuned to listen for the wake word, but without actually recording or transmitting data to the cloud. Partnering with Shaip gives you the advantage of working with experts. With our extensive experience using AI and ML technology in developing voice assistant training, we help you can eliminate privacy risks, improve user experience, reduce development costs and enhance scalability.

Valuable Tips on How to Pick the Right Wake Up Words / Trigger Words

Choose Words with Diverse Sounds

Different phonemes generally create a more distinct signature and ensure better accuracy in the results. Hence, pick phrases in your data that produce various sounds.

Leverage a Suitable Prefix with Your Words

Make wake words more effective by affixing them with prefixes like “Hi,” “Hello,” "Hey," or "OK." It will keep the wake word unambiguous & ensure no accidental matching occurs when using trigger word in regular speech.

Use Phonemes to Build Your Trigger Words

Make your wake words a combination of at least six phonemes that are easily discernible by a machine and easy to say by humans. For instance, "Alexa" has six phenomes while “Ok Google” has eight phenomes.

Avoid Using Single Word

Do not make the mistake of using a single word as your wake word. Wake words must be long enough to be distinct.

Simple & Unique Words

Ensure the trigger words that you create must be simple and unique so that they can be easily remembered.

Avoid Long Phrases

Longer multi-word wake phrases are hard to pronounce and make the process unnecessarily harder.

Limitations of Wake Word Training Data

Confusion due to Use of Multiple Utterances

A wake word model is generally trained to recognize a no. of different utterances, so that it can respond to different invocations. However, having too many distinct wake words can simply activate the speech pipeline without you knowing which utterance did the user spoke.

Less Accurate Results Due to External Surroundings

Factors like noise, distance, and variations in accents and language makes accurate hotword detection harder and complex for your AI model.

Building Accurate Wake Words for your Brand

Train Train

Our experience in voice technology helps us develop always-listening tailored wake words and branded wake phrases quickly. With voice recognition in tandem with natural language processing understanding, ML algorithms help transcribe speech & execute voice commands effectively.


We focus on rapidly developing wake word prototyping to ensure customization of the branded word. A prototype acts as a proof of concept and helps in accurate training, faster time to market, accelerated testing, and elimination of risks.

Grow Grow

Experience uninterrupted growth and unhindered customer engagement with an exceptional voice assistant. We provide multilingual speech recognition capabilities so that the application can accurately spot words and phrases even in high-noise environments.

Rapid design, development, & deployment

Training, developing, and deploying always-listening custom wake words need not be tedious and time-consuming. With the right assistance from Shaip’s expert technology experts, you can simplify and reduce the time-to-market effectively. In addition, our data collection, labeling, and annotation experience work in your favor to deliver wake words within weeks.

Features of Wake Words Training and Deployment 

Customized brand wake words

Customized Brand Wake Words

A branded wake word is often associated with value and performance. It is time you leveraged the immense benefits of having custom branded wake words work in your favor. Own up your brand and develop a tailored wake word or a phrase that projects your brand in the best light. At Shaip, we can help your customers use your brand name with every interaction with branded incantation with their voice assistants.

Command or phrases Spotting

Going beyond wake word is phrase spotting, allowing users to employ natural language to control their voice-activated devices. Shaip has extensive experience helping small to large businesses develop applications that can process lengthy phrases with zero latency and increased accuracy.

Command or phrases spotting
Embedded phrase detection

Embedded Word or Phrase Detection

Shaip’s developers help brands provide enhanced voice experience to their customers by providing embedded keyword or phrase detection. We ensure privacy, zero-latency, and high accuracy by having the wake word engine technology process the multiple wake words within the browser and not on the cloud.

Understanding the Concept of Data Diversity

What is Data Diversity?

It is a way of collecting crucial user data such as their identity, country of origin, age, sex, language, accents, etc. Data diversity is used for improving user-oriented algorithms to achieve more accurate outcomes.

Data usually tend to generate built-in biases. Therefore, when we collect data from diverse sources, the bias in the results significantly reduces. 

Here are a few parameters of data diversity that Shaip addresses while building wake words and other conversational commands.

Using AI to improve business performance through customer experience

The wake words are the phrases that activates your voice-enabled systems and put them into the listening mode to take instructions from users.

Invocation name is the keyword used to trigger a specific “skill” of the software. The invocation name can also be names of people or places and can be combined with an action, command or question. All the custom skills should have an invocation name to start it.

Utterances are phrases used by the users to make request to your voice-command software. The software identifies the user’s intent from the given utterance and further responds accordingly.

Natural language processing or NLP is a convergence of artificial intelligence and computational linguistics that is responsible for interactions between machines and natural languages of humans. Leveraging NLP algorithms, the software analyze, understand, alter, or generate natural language for your AI model.

Wake up word, Utterances, Trigger Words, Hot Words, Invocation Words

 A sentence is a group of words that expresses complete meaning or conveys an entire idea. A sentence could be simple, complex, or compound in nature, and it can be expressed in written or spoken form. 

An utterance, on the other hand, is a unit of speech that does not usually convey the entire meaning or thought, and is replete with pauses and silences.

Examples of utterances: 

  1. ‘Let me present to you….this is the statistics in the region’
  2. ‘Show me the latest movie……the one that was released last week.’
  3. ‘Is the store on 22nd Street open now……the one next to the bank.’

Alexa comes with several built-in microphones that detect and recognize the wake word by ignoring the background noises. To prevent false negatives and false positives, Alexa is programmed to turn on hearing only after detecting the wake word ‘Alexa.’

A wake word is any programmed phrase that causes the speech assistant to start listening and processing the user’s requests. Any speech assistant is trained on real-world interactions using Artificial Intelligence and Natural Language processing in which speech is converted into phrases, words, and sounds.
