Nina Offers More Natural, Intuitive Self-Service Interactions

Nina knows you. She knows your voice. She also understands want you want based on the natural phrasing of your request. Nina streamlines logging in, finding features in the app, asking questions and performing transactions using the power of talking, texting or tapping—making mobile interactions easier, more productive and enjoyable.

Beyond Simple Speech Commands, Nina Engages Customers in Conversation

Nina can be as interactive as you’d like, from simple requests in the users’ own words that drop them in the intended location, to a continued conversation with multi-turn and contextual dialogues. Conversational dialogue requires a complex set of technologies working together to deliver an effective and engaging user experience. Nina abstracts the complexity, offering natural, intuitive service interactions.

Multimodal Input/Output for Maximum Flexibility via Talk, Type and Tap

A multimodal interface is a must for the consumer experience. Nina has been designed specifically for mobile app front-ends to support inputs via speech, tap and text—giving the user the flexibility to choose the interaction type that they prefer and the flexibility to move within a given transaction between multimodal talk, type and tap.

Nina Product Details


Nina Components

Nina is comprised of:

Nina Virtual Assistant Persona: A Reusable Reference UI
Nina offers a complete virtual assistant persona, which developers can either utilise for their app or take the available source code to quickly create a custom persona, including changing visual elements such as being awake, asleep, listening, processing or answering a request. Customers can choose from a range of existing Nuance text-to-speech voices or develop a custom TTS voice.

Nina Virtual Assistant SDK: Shorten Implementation Times
To enable fast integration of virtual assistant capabilities into mobile apps for Apple iOS and Android, the Nina Virtual Assistant SDK offers binary APIs that abstract the complexity of the multimodal and natural language interactions between the client and the cloud. Nuance provides a sample application (instantiation of the APIs) and source code which demonstrates how the APIs are used and how it interacts with the hosted service.

Nina Virtual Assistant Cloud: Hassle-free Innovation
A Nuance hosted service that provides Nina's power and intelligence, including access to Nuance’s industry-leading speech recognition, Text-to-Speech (TTS), Natural Language Understanding (NLU), interactive dialogue management and voice biometrics services. The cloud offers scalable, redundant and PCI compliant servers with guaranteed SLAs of 99.95% uptime. Hosting allows customers to focus on building a better mobile experience for their users, without the additional overheads needed to install, deploy and manage hardware, software and network updates.

What's In the Nina Cloud

Nuance VocalPassword: The Leading Voice Biometrics Engine
Nuance VocalPassword, the world’s most deployed voice biometric solution, delivers easy and secure authentication by having users speak a simple passphrase, such as “My voice is my password,” eliminating the need for passwords or PINs when authenticating to a mobile device, call centre or web portal.

Nuance Recogniser: The Top Natural Language Understanding (NLU) Engine
In any automated customer interaction, voice recognition is a crucial starting point, but real understanding is the essence of meaningful, natural interaction. Nina is built on Nuance Recogniser, the most widely deployed enterprise speech-recognition technology in the world. Beyond just matching the words you say against a predefined list, Natural Language Understanding (NLU) allows your apps to understand what your customers mean.

Conversational Dialogue: Understands Meaning, Context and Intent
Nina puts the user in control of the conversation by offering a personalised experience informed by prior conversational cues, just like when speaking with another human being. It can handle information provided in any sequence and has the ability to understand what information is needed and prompt accordingly to complete an interaction.

Nuance Vocaliser: Add Text-to-Speech (TTS) To Your App without the Bloat
Nuance Vocaliser, the leading text-to-speech engine, offers spoken responses to text inputs, enabling a conversation with a mobile app. Using TTS APIs mean that you don't need to bloat your app with pre-recorded audio and can deliver better audio playing capabilities than currently exist on such devices. Choose from a variety of TTS voices or build your own custom voice that best suits your brand.

Reporting: Actionable Insight for Making Your App Even Better
Nuance Mobile Reports provide actionable insights to help you optimise performance and make better business decisions. With Mobile Reports, you can see a snapshot of real-time application metrics in a dashboard, run historical summary reports, drill down to a sample list of sessions that exhibit certain characteristics, and see detailed information for a particular session, offering insight into key trends in user behaviour.
