Product Introduction

1. Universal-Streaming is a real-time speech-to-text API designed for voice agents, offering ultra-fast transcription, high accuracy, and configurable endpointing to enable seamless voice interactions. It provides immutable transcripts with a 300 ms P50 latency, ensuring downstream systems receive stable data without mid-stream revisions.
2. The core value lies in its ability to balance speed, accuracy, and cost-efficiency at scale, with transparent pricing starting at $0.15/hour and support for unlimited concurrent streams. It eliminates the need for pre-purchased capacity or complex infrastructure management while maintaining enterprise-grade security.

Main Features

1. Ultra-low latency with 300 ms P50 word emission ensures real-time responsiveness, enabling voice agents to process and act on user inputs almost instantaneously. Immutable transcripts remain unchanged from the initial emission, preventing downstream errors caused by mid-stream corrections.
2. Intelligent endpointing combines acoustic, semantic, and silence detection to reduce end-of-turn delays by 21% compared to traditional methods, minimizing interruptions in conversations. Configurable silence thresholds and confidence parameters allow fine-tuning for specific use cases like call centers or voice assistants.
3. Superior accuracy in critical areas includes a 12% overall reduction in word error rates, 21% fewer alphanumeric errors (emails, IDs), and 5% better proper noun recognition compared to alternatives like Deepgram Nova-3. Automatic punctuation, casing, and formatting ensure clean outputs for LLM processing.

Problems Solved

1. Addresses the latency-accuracy tradeoff in real-time transcription by providing sub-500 ms finalization while maintaining >91% word accuracy, critical for voice agents requiring immediate yet reliable responses.
2. Targets developers building conversation intelligence tools, customer support automation, or real-time voice assistants that demand high concurrency (5–50,000+ streams) without performance degradation.
3. Ideal for scenarios like contact center analytics, where agents need accurate capture of alphanumeric codes, or telehealth platforms requiring natural turn-taking between patients and AI assistants.

Unique Advantages

1. Outperforms competitors like Deepgram Nova-3 with 2x faster P99 latencies and higher accuracy in alphanumerics (94.6% vs 93.3%) while costing 40% less per hour. Unlike tiered pricing models, it charges purely based on session duration without hidden fees.
2. Patent-pending endpointing technology uses multimodal signals (speech patterns + content context) to detect conversation turns 300 ms faster than silence-only detection. The speed↔post-processing dial lets developers prioritize either real-time emission or polished final transcripts.
3. Enterprise-ready scalability ensures consistent performance across unlimited concurrent streams, backed by real-time analytics for monitoring throughput and error rates. Regular model updates via the changelog guarantee continuous improvement without API changes.

Frequently Asked Questions (FAQ)

1. How does Universal-Streaming handle sudden spikes in concurrent streams? The API automatically scales infrastructure to support unlimited streams with no performance degradation, eliminating manual capacity planning or overage charges.
2. What makes the endpointing system more effective than silence detection? It analyzes speech content and acoustic patterns to predict natural conversation breaks, reducing end-of-turn latency by 21% while avoiding premature cuts during brief pauses.
3. Can the model format specialized terms like product names or IDs? Yes, it achieves 94.6% accuracy on alphanumerics and proper nouns through domain-adaptive training, automatically applying casing and punctuation to outputs like "Model-X2024" or "support@company.com".
4. How is pricing calculated compared to other providers? Costs are based solely on total session duration at $0.15/hour, unlike competitors that charge per audio-minute or impose concurrency limits. No fees apply for idle time during pauses.
5. What security certifications does the platform offer? Universal-Streaming complies with SOC 2 Type II, GDPR, and CCPA, with data encrypted in transit (TLS 1.3+) and at rest (AES-256). Enterprise clients can request private cloud deployments.
