Voice AI chatbot for WordPress: speak instead of typing
SleekAI's chatbot accepts speech input through the browser's SpeechRecognition API and speaks answers back via SpeechSynthesis, while reading live post, postmeta, and custom table data. Bring your own OpenAI, Anthropic, Google, or OpenRouter key.

Voice without the SaaS lock-in
Most voice chatbots route audio through a hosted pipeline: client streams microphone audio to a vendor server, vendor transcribes via Whisper or Deepgram, sends the transcript to GPT, gets a reply, runs it through ElevenLabs, streams audio back. Every step is metered, every step adds latency, and the entire conversation passes through one or two third parties before it reaches your WordPress site.
SleekAI takes a leaner approach. The widget uses the browser's native SpeechRecognition API to capture and transcribe speech locally, sends just the text to your provider key, then plays the reply back through SpeechSynthesis. No third-party transcription server, no extra subscription, no vendor in the middle. The only network call is the same chat completion request a text-only bot would make.
Because the model still reads your live WordPress data through SleekAI's variable mapper, a spoken question about an appointment slot or a course module lands with the same factual grounding as a typed one. Display conditions let you scope the voice bot to specific pages (the accessibility page, the contact page, a kiosk template), and multibot lets text and voice bots coexist with different system messages.

Features
What SleekAI gives you for Voice Chatbot
Browser-native speech
The widget calls the Web Speech API directly, so audio never leaves the visitor's device unencrypted. Only the resulting text transcript is sent to your provider key, the same as any other text chat request.
Speakable replies
Replies are played back through SpeechSynthesis with the visitor's choice of system voice. You can pick a default per chatbot, including locale-specific voices for non-English sites.
Accessibility wins
Visitors who struggle to type, including older users and people with motor impairments, can interact with your site by voice. Combined with WCAG-friendly contrast, voice flows widen the audience for forms and lookups.
Use cases
Where voice chatbots earn their keep
Clinics and salons
Patients book appointments by voice from a phone in the waiting room or a kiosk at reception, without filling out a typed form.
Hands-free lookups
Drivers checking dealership hours, parts availability, or service slots while driving can ask without taking eyes off the road.
Inclusive interfaces
Sites serving older users, vision-impaired visitors, or motor-impaired users gain a voice-first path that complements existing forms.
The bigger picture
Why owned voice beats SaaS voice
Voice AI from SaaS vendors looks like a single product but is really a stack of metered services glued together. The customer signs up for one subscription and ends up paying for transcription minutes, model tokens, synthesized audio seconds, and a per-seat fee on top. The pricing pages call this innovation.
From the merchant's side, it is four meters running at once and a vendor in the middle of every patient or shopper conversation. The browser already ships free APIs for both ends of the voice loop. SpeechRecognition is built into Chrome, Edge, Safari, and Opera.
SpeechSynthesis is everywhere. The only piece that genuinely needs a paid API is the model itself, and the merchant should be paying the model provider directly through their own key. SleekAI assembles those pieces inside WordPress without inventing a new meter.
The voice button works for the same per-conversation cost as a typed message. The data the model sees is still the real product, appointment, or membership data on the site. And when a voice flow does not justify itself, it can be turned off per chatbot without uninstalling anything.
Owned beats rented when the underlying infrastructure is already free in the browser.
Questions
Common questions about SleekAI for Voice Chatbot
No. SleekAI uses the browser's free Web Speech API for both speech-to-text and text-to-speech, so there is no per-minute audio charge. You pay only for the chat completion tokens at your provider's standard text rates, same as a typed conversation.
Chrome, Edge, Opera, and Safari (iOS 15+ and macOS 14+) support the Web Speech API. Firefox supports SpeechSynthesis for replies but has limited SpeechRecognition support. SleekAI gracefully falls back to text input when recognition is unavailable, so non-supported browsers still get the chat.
No raw audio is uploaded by SleekAI. The browser's local recognition engine produces a text transcript, and only that transcript is sent to your provider for completion. On Chrome and Edge, recognition may use a Google-hosted engine under the hood, which is a browser behavior and is the same as any other site using the API.
Yes. SpeechSynthesis exposes the voices installed on the visitor's OS, so you can pick a preferred voice per chatbot. On macOS that includes Samantha and Daniel, on Windows it includes Microsoft Aria, and on iOS the high-quality Siri voices when granted. The widget falls back gracefully.
Yes. Multibot mode runs several chatbots on one site with independent system instructions and display conditions. A common setup is a typed bot for the help center and a voice-first bot for a kiosk template, each scoped through page conditions and each with its own preset questions and greeting.
Yes on iOS Safari 15+ and Chrome for Android. The mobile keyboards already have dictation, so the marginal value of voice on mobile is smaller, but the explicit mic button in the widget makes the interaction more discoverable than relying on keyboard dictation icons.
Mostly yes. SpeechSynthesis pronounces currencies and digits competently in major languages, but it can stumble on long SKU codes or compressed jargon. A common trick is to add a short pause hint in the system prompt asking the bot to spell long codes letter by letter when speaking, and to round prices for the spoken reply.
Patient identifiers should not be spoken into the bot unless your provider account is set up for it. SleekAI gives you the wiring; HIPAA compliance still depends on the provider you use (OpenAI offers a BAA on Enterprise plans, Azure OpenAI supports BAAs). For non-PHI questions like appointment slots and clinic hours, voice is safe.
