AI Virtual Assistant
Companies are deploying AI virtual assistants to automatically address the queries of millions of customers and employees around the clock. With Riva speech and translation AI microservices, these assistants provide helpful and natural responses at every turn of the conversation despite background noise, poor sound quality, and diverse speaker dialects and accents.
Agent Assist
Consumers expect contact center agents to resolve their issues quickly and efficiently. To meet these expectations and deliver the best customer and agent experiences possible, enterprises across industries are implementing agent-assist technology powered by Riva speech and translation AI.
Transcription
With hundreds of millions of online meetings held daily, video conferencing has become an indispensable tool for enterprises. With Riva real-time transcription, video conferencing applications achieve impressive accuracy in live captioning and meeting summarizations, accommodating users with worldwide accents and diverse, domain-specific vocabulary.
AI Translation
In the global economy, businesses operate across many countries and serve customers with diverse linguistic and cultural backgrounds. This diversity in global languages poses a unique challenge in finding native speakers or training employees in multiple languages. Riva translation empowers accurate and effective communication, facilitating smooth global interactions.
AI Robot
AI robots are increasingly found in hospitals, airports, and retail stores worldwide. They aid frontline workers by handling daily repetitive tasks in restaurants and manufacturing facilities, assist customers in locating items in stores, and support physicians and nurses in patient care. With Riva, it’s easy to add speech and translation AI to service robots.

AI2Labs
In 2021, AI2Labs spun off from Yoozoo Games as a local tech startup in Singapore. AI2Labs innovates, experiments, and develops AI products and applications, enabling efficient processes and improving sustainability and business outcomes.
AI2Labs integrated Riva into their Speakr—domain-specific speech AI—speech recognition API to accommodate the intricacies of Asian speech and business domains and achieved state-of-the-art Singlish translation accuracy.
Avaya
Avaya specializes in cloud communications and workstream collaboration solutions, providing unified communications, contact center, communications platform as a service (CPaaS), and services with their OneCloud platform.
Avaya integrated the NVIDIA Riva speech-to-text engine for real-time captions at scale. Riva enables better transcription quality, lower word-error rate, and economical delivery.
C-DAC
For over 10 years, the Applied AI Group at C-DAC in Pune, India, has focused on research and development of speech technology. They’ve successfully created a cutting-edge speech-to-text (STT) system for Indic languages such as Hindiand Marathi. The group continues to advance their work by exploring AI-enabled, open-source deep learning frameworks, libraries, and tools for creating STT and speech-enabled applications for other Indic and low-resource languages. Experiments were conducted using various neural network architectures and topologies from NVIDIA’s open-source NeMo framework, with Citrinet and Conformer-CTC network topologies proving to be effective in building and training neural acoustic models for speech recognition. These models were trained on single- and multi-node Param Siddhi AI systems, optimizing training time and performance. Finally, the models were deployed for real-time and batch-mode inference using the Riva GPU-accelerated production pipeline.
