Build Audio Search That Finds Sounds by Similarity, Not Metadata
Zilliz Cloud powers real-time audio similarity search across fingerprints, speech, music, and environmental sounds. Convert audio to vector embeddings and search billions of sound samples in under 10ms — with the accuracy your application demands.
Audio Search Applications Powered by Zilliz Cloud
Build intelligent audio search systems that match sounds by acoustic similarity across every format — speech, music, environmental audio, and beyond.
Music Identification and Discovery
Build a music recognition system that identifies songs from short audio clips. Convert audio fingerprints into vector embeddings and match them against catalogs of millions of tracks in milliseconds — powering Shazam-like experiences at any scale.
Voice Query and Speech Retrieval
Enable users to search audio archives using spoken queries. Convert speech to embeddings with models like Whisper and retrieve semantically similar recordings across call centers, podcasts, and meeting archives — finding relevant content without exact transcripts.
Audio Copyright Detection
Detect copyrighted audio across user-generated content platforms. Match uploaded audio against a rights-holder database using acoustic fingerprints to flag potential infringement automatically — reducing manual review time and protecting intellectual property at scale.
Environmental Sound Monitoring
Build systems that detect and classify environmental sounds in real time — gunshots, glass breaking, alarms, or equipment failures. Match incoming audio against known sound signatures to trigger instant alerts for security and industrial safety applications.
Medical Audio Diagnostics
Analyze respiratory sounds, heartbeat recordings, and vocal biomarkers for health screening. Compare patient audio samples against reference databases of known conditions to assist clinicians with early detection and remote patient monitoring.
Podcast and Broadcast Search
Build searchable audio archives across thousands of hours of podcasts, broadcasts, and lectures. Extract audio embeddings per segment and enable listeners to find specific topics, speakers, or sound events without manual tagging.
Automotive Voice Command Matching
Deploy in-vehicle voice recognition that matches driver commands against a database of known intents. Use audio embeddings to handle accent variation, background noise, and natural speech patterns — delivering reliable results in noisy cabin environments.
Audio Quality Assurance
Automate detection of defects in manufacturing by analyzing machine sounds. Compare production-line audio against baseline embeddings of normal operation to identify anomalies — catching bearing wear, motor faults, and assembly errors before they cause downtime.
Why Zilliz?
Why AI Teams Choose Zilliz Cloud for Audio Search
Audio search at production scale requires a database that can index billions of audio embeddings, execute similarity queries in single-digit milliseconds, and handle concurrent streams from real-time applications. Zilliz Cloud delivers all three — purpose-built for vector workloads.
100K+QPS
Handle concurrent audio queries from millions of users
Audio identification services process bursts of simultaneous requests — every user holding up a phone to identify a song is a query. Zilliz Cloud sustains 100K+ queries per second with stable p99 latency, so your recognition service stays responsive during peak moments.
10B+Vectors
Index entire audio catalogs without partitioning workarounds
Global music libraries, podcast archives, and call center recordings generate billions of audio embeddings. Zilliz Cloud handles 10B+ vectors in a single deployment — so your audio search covers every track, every recording, and every clip without manual sharding.
-10xCost
Cut audio search infrastructure costs dramatically
Running separate systems for audio feature extraction storage and similarity matching inflates infrastructure spend. Zilliz Cloud's tiered storage and automatic resource management reduce audio search infrastructure costs by up to 10x compared to self-managed vector database deployments.
< 10msLatency
Return audio matches before the listener notices a delay
Audio identification must feel instant — users expect a match in the time it takes to hum a few bars. Zilliz Cloud returns similarity results in under 10ms, fast enough for real-time audio fingerprinting, live broadcast monitoring, and interactive voice applications.
Hybrid search out of the box
Combine audio vector similarity with metadata filters — genre, duration, language, speaker ID — in a single query. No need to stitch together separate systems for acoustic matching and attribute filtering.
Automatic and elastic scaling
Automatically scales compute and storage as your audio index grows — handling catalog expansions and traffic spikes from viral moments with no capacity planning or index rebuilding required.
Native multi-tenant architecture
Built-in tenant isolation lets you run audio search for multiple clients, apps, or content libraries on the same platform — without cross-tenant data leakage or noisy-neighbor performance issues.
Ease of use
Go from zero to production-ready audio search in minutes. Zilliz Cloud manages the infrastructure and scaling — so your team focuses on audio models and search quality, not cluster operations.
Multi-cloud flexibility
Run on AWS, Azure, or GCP across 30+ regions worldwide — keeping your audio search infrastructure close to your users and within your cloud and data residency strategy.
Enterprise-grade reliability and compliance
99.95% SLA with SOC 2, ISO 27001, GDPR, and HIPAA compliance — plus regional failover and BYOC support for audio workloads handling sensitive voice and health data.
