Why Leopard Speech-to-Text?

Speech-to-text APIs require enterprises to send their data to a 3rd party cloud, giving away control over their data and product.

Leopard Speech-to-Text offers the same performance with no compromises.

Don't leave any data behind

Creating new possibilities for your content, product, and database

Just like “best” cloud transcription APIs…

Leopard Speech-to-Text offers cloud-level accuracy, model customization, and cross-platform support…

…with no compromises

…without sacrificing privacy, reliability, and affordability, enabling use cases that were impossible before.

Speech-to-Text Model Adaptation

Boost accuracy with custom models

Customize pre-trained speech-to-text models instantly by adding domain-specific vocabulary and boosting frequently-used words on a self-service platform, achieving the highest possible accuracy.
Speech-to-text APIs transfer voice input to the cloud to transcribe it into text, creating privacy, and reliability issues and additional costs.
Cross-platform support

Create seamless experiences

Deploy Leopard Speech-to-Text anywhere and offer seamless experiences across devices, mobile apps, web browsers, on-premise, cloud, or all.
Privacy by design

Do not rely on “check the box” compliance models

Process voice data without sharing it with 3rd parties, ensuring compliance with GDPR, HIPAA, CCPA, and more - including any policies that come in the future.
No downtime and zero latency

Develop dependable products

Build reliable products with predictable response times by bringing speech-to-text closer to your data to bypass network latency, congestion, outages, or throttling.
Cost-effective at scale

Scale your business, not cloud providers’

Do not bear the cost of running bulky models in the cloud. Big Tech uses on-device speech-to-text for their products because running large models in the cloud is costly, even for them.

What is speech-to-text?

Speech-to-text (STT), also known as Automatic Speech Recognition (ASR) and Open-Domain Large Vocabulary Speech Recognition (LVSR), refers to the technology and methodologies that convert voice data into text.

How does on-device speech-to-text differ from cloud-based speech-to-text?

Cloud-based speech-to-text APIs send voice data to vendors’ servers, where the transcription engine resides. On-device voice processing brings voice recognition where voice data is, eliminating all the steps related to cloud processing.
