The timing cannot be more perfect to write this article! Open AI’s GPT 4.0 just got released and it unlocks new possibilities in how we interact with AI models and applications. Its launch completely falls in line with the tone and experience set by Samantha in Her, with a voice-enabled AI that is more vibrant, enthusiastic, and humorous. It’s fair to say that now is also the ideal time to discuss the importance of customized speech command datasets in training AI models.

Why Speech Recognition Technology Matters Now More Than Ever?

Let’s look at our home, our environment, and things around us. We have connected all possible electronic devices to the internet. More importantly, we have empowered devices and gadgets with Automatic Speech Recognition technology.

The living room light bulb can now change hues and moods, televisions can change channels and volumes, and refrigerators can defrost with voice commands. To paint a more vivid picture, here are some intriguing numbers:

• Over 125.2 mn users preferred voice search in the year 2023.
• Over 50% of the users around the world prefer voice search options.
• Every single month, voice search records over 1 billion commands and interactions.
• The speech recognition technology market is estimated to be valued at around $19.57bn by the year 2023.

With voice search becoming an integral part of our lifestyle, the onus is on developers and enterprises to make the retrieval of results as simple, precise, and seamless as possible. This is exactly why today’s topic holds significance in this context.

Classic Use Cases Of Speech Recognition Technology

While we are already interacting with a voice-enabled device on a daily basis through devices like Alexa or applications like virtual assistants, there are deeper use cases of this technology that dictate customized speech command datasets. This includes:

• Transcription services in healthcare, financial, or medical sectors as they require industry-specific jargons and vocabulary for precision results
• Language learning apps, where real-time analysis and feedback can happen when assessing the speaking capabilities of users
• Accessibility tools to ensure seamless computing experiences for differently abled people for an inclusive and wholesome ecosystem
• Customer service and basic assistance delivery to eliminate redundant tasks from the shoulders of humans
• Hands-free navigation in vehicles to ensure drivers do not focus on their screens trying to use maps or navigation apps and instead use voice commands to get information they are looking for.

What Are Customized Speech Command Datasets And Why Are They Required?

When a device wakes up when a user utters, “Alexa,” or, “Hey, Siri,” this is mainly due to automatic speech recognition training. Now, add a layer to this. Not everyone utters or pronounces the same way. There are accents, ethnicities, and dialects in place. Besides, users tend to assign nicknames to their devices as well. The gadgets need to respond to all such varied queries and contexts.

All this is enabled with the help of customized speech commands.

In simple words, such datasets are collections of super-specific audio recordings that are meant to trigger certain actions and processes.

The Anatomy Of Customized Speech Command Datasets

For algorithms and models to respond promptly to distinct commands, voice recognition training in diverse aspects is inevitable. So, the typical anatomy of a dataset involves:

Diverse vocabulary in speech datasets

This is the inclusion of contextual and relevant words pertaining to specific applications. For instance, speech datasets for healthcare would feature medical-related vocabularies such as diagnosis, MRI reports, patient care and more while that of a legal use case would feature words like defendant, injunction, pro bono, and more.

Annotation accuracy in speech datasets –

Precise labeling of voice datasets is crucial to prompt accurate results. While models find it comparatively easier to process longer commands, short instructions like yes, no, stop, go, play, and more require additional information on whether they are questions, sarcastic comments, instructions, or more.

Annotation removes ambiguity in speech datasets, strengthens context, and optimizes quality.

Audio Diversity

The accent of an Indian is very different from that of a Mexican or a German. Even a common language like English attracts different pronunciation of the same words due to innate familiarity with the mother tongue. An AI model needs to acknowledge and process such diversity in voices, accents, pronunciations, tones, and more to function and deliver relevant results.

The Advantages Of Customizing AI Training Data For Voice Recognition Technology

Statistics reveal that voice search models deliver an accuracy of 93.7% in the results. However, this could be after prolonged periods of training over diverse datasets. Despite this, there is a scope to decrease the margins of errors.

This is where customized speech commands datasets become indispensable. By sourcing customized datasets from service providers, you can ensure your AI model:

• Delivers domain, industry, or purpose-specific results with improved accuracy
• Adapts to the ethnicities of users and blends well with their accents for personalized responses
• Improves user experience by responding with humor, sarcasm, astonishment, melancholy and other emotions
• Learns to listen to users in diverse environments such as noisy backgrounds, from muffled or distorted microphones, and more

Of all these, one of the best advantages of sourcing customized speech commands datasets for your models is eliminating risks involved with privacy and security of users. Since service providers like us – Shaip – ensure ethical practices in sourcing and curating bespoke voice data, not only bias is minimized but datasets are shared with consent as well.

Specifically, in fields like healthcare and legal, sensitivity of data is critical. This is exactly why leveraging AI training data service providers work wonders for enterprises and startups in the AI race.

So, if you’re looking for quality datasets to train your models, we recommend getting in touch with us to discuss your scope. We will get started with sourcing and delivering high-quality, customized speech commands datasets for your visions, regardless of the scale of requirement.
