Real-time voice UI platform for production-ready speech
Speechly is a real-time voice UI platform that converts live speech into intent, slots, and transcripts for web and mobile apps, ideal for product teams building conversational voice features; pricing includes a free tier with usage caps and paid plans for higher request volumes and enterprise support.
Speechly is a real-time Voice & Speech platform that turns spoken input into intents, entities (slots), and streaming transcripts for web, mobile, and embedded applications. It focuses on low-latency, streaming voice UIs that run in the browser or on-device with a client SDK and a cloud runtime. Speechly's key differentiator is deterministic streaming NLU that outputs increments of intent and slot updates as users speak, serving developers building voice-enabled search, forms, and commands. Pricing is accessible with a free tier for development and paid tiers that scale by monthly active users or request volume.
Speechly is a real-time voice UI platform focused on turning spoken input into structured intent, slot and transcript streams suitable for production apps. Founded in 2016 in Finland, Speechly positions itself as a developer-first solution for embedding voice interactions into web, mobile, and IoT products. Its core value proposition is deterministic, low-latency streaming speech recognition plus natural language understanding (NLU) that emits partial results while a user speaks, enabling responsive conversational interfaces without waiting for full utterances.
Speechly's feature set centers on streaming ASR, streaming NLU, and SDKs that run in browsers and native apps. The Speechly Client SDKs (JavaScript, React, Android, iOS) provide a live audio pipeline and a WebSocket-based connection to Speechly's Cloud or self-hosted runtime; they stream partial transcripts and token-level intent/slot updates. The platform supports domain models where you define intents and slots via the Speechly console and train language models; it also provides explicit voice activity detection (VAD), session management for multi-turn flows, and deterministic response hooks so apps can react to partial intents before the user finishes speaking.
Additionally, Speechly offers a local inference option (Edge) for reduced latency and privacy-sensitive deployments. Pricing is tiered with a free tier intended for development, a Growth/Pro tier for small-production usage, and Enterprise/Custom pricing for high-volume or on-premise needs. The free plan includes a limited number of monthly audio minutes and access to SDKs and the console for model creation.
Paid plans add higher monthly audio quotas, SLA options, and team features; exact paid-plan prices are published on Speechly's website or via sales for enterprise. For very large deployments, Speechly offers custom contracts with dedicated support, higher concurrency, and the option for on-prem or private-cloud deployment which are quoted per-customer. Product teams, voice UX designers, and mobile engineers use Speechly to add command-and-control and voice search capabilities to apps.
For example, a Senior Mobile Engineer uses Speechly to reduce user input time by 40% when filling forms via voice, while a Voice UX Designer deploys it to prototype multi-turn voice flows for an e-commerce cart. Speechly competes with cloud ASR+NLU stacks like Google Speech-to-Text + Dialogflow, but distinguishes itself by combining streaming ASR and deterministic streaming NLU in one developer-focused package for real-time voice UIs.
Three capabilities that set Speechly apart from its nearest competitors.
Which tier and workflow actually fits depends on how you work. Here's the specific recommendation by role.
Speechly is useful when one person needs faster output without adding a complex workflow.
Speechly should be tested for collaboration, quality control, permissions and repeatable results.
Speechly is worth buying only if the pilot shows measurable time savings or quality gains.
Current tiers and what you get at each price point. Verified against the vendor's pricing page.
| Plan | Price | What you get | Best for |
|---|---|---|---|
| Free | Free | Limited monthly audio minutes and development access, single project | Developers experimenting or early prototypes |
| Growth | $49/month | Higher monthly minutes, commercial use, basic support | Small production apps and startups |
| Pro | $299/month | Larger minutes quota, priority support, multiple projects | Growing teams with production traffic |
| Enterprise | Custom | Custom quotas, SLA, on-prem or private cloud options | Large businesses needing SLAs and integrations |
Scenario: A small team uses Speechly on one repeated workflow for a month.
Speechly: Free | Freemium | Paid | Enterprise ·
Manual equivalent: Manual review and execution time varies by team ·
You save: Potential savings depend on adoption and review time
Caveat: ROI depends on adoption, usage limits, plan cost, output quality and whether the workflow repeats often.
The numbers that matter — context limits, quotas, and what the tool actually supports.
What you actually get — a representative prompt and response.
Choose Speechly over Google Cloud Speech-to-Text if you need deterministic streaming NLU that emits partial intents during live speech.
