Voice Assistants That Understand Czech in 2026 (and Why Siri Still Doesn't)

TL;DR:

• Siri doesn't speak Czech. Apple's feature availability page for iOS 27 lists 37 countries and regions for Siri, and neither Czech nor Czechia is among them (checked October 29, 2026). Apple hasn't announced a date.
• Your iPhone already understands Czech in one place: keyboard dictation. It has no automatic punctuation in Czech, and Voice Memos and Notes can't transcribe Czech recordings.
• Google's Gemini app understands Czech, and Gemini Live has spoken Czech since January 2025. It's a conversation partner first; your to-do list still lives somewhere else.
• Codot understands spoken Czech on iPhone and Android. It's our product, so read that section with that in mind. You say what's on your mind and it becomes tasks, events and notes.

Codot, a voice-first personal AI assistant, is our product, so we have an interest in this question. The facts about Apple and Google below come from their own pages, linked and checked on October 29, 2026. We haven't run a formal accuracy test of any assistant in Czech, so we don't rank them by recognition quality.

If you live in Prague or Brno and own an iPhone, you've probably given up on Siri or switched it to English. The second option works until you need to say "remind me to call Mrs. Dvořáková about the Vinohrady flat," and Siri, listening in English, turns the name and the street into something you'll never find again. That's the case this article is about: you want to speak Czech to your phone and end up with something saved.

Does Siri speak Czech in 2026?

No. The Siri section of Apple's iOS 27 feature availability page lists the countries and regions where Siri works. There are 37 entries, from Australia to Vietnam, including Finland, Norway, Sweden and Türkiye. Czechia isn't there, and Czech doesn't appear as a language in brackets next to any country either. Slovak is missing too, as is Siri in Polish for users in neighboring Poland.

Apple introduced a rebuilt "Siri AI" in June 2026. Its Czech newsroom page doesn't say when or whether Czech is coming, and we haven't found any Apple statement that gives a date. At least one Czech Apple news site, Letem světem Applem, has written that it wouldn't bet on Czech in iOS 27. We'd plan your next year as if Siri stays without Czech, and treat any change as a bonus.

Many people set Siri to English and live with it. That's fine for "set a timer for ten minutes." It breaks on Czech names, street names and anything you'd naturally say in Czech in the first place.

Which voice assistants understand Czech?

Status on October 29, 2026, from each company's own documentation:

Google is the strongest of the big platforms here. Its Gemini help page lists Czech among the languages of the Gemini web app, and the Google Czech blog announced on January 22, 2025 that Gemini Live speaks Czech and Slovak on Android, with iOS "soon." At launch you had to set Czech in the app's language settings, and Czech reviews noted that you couldn't start it by voice in Czech. We couldn't confirm whether the wake word works in Czech today.

What none of the big assistants is designed for is the task list. Gemini will happily talk to you in Czech about your week. Getting "pick up the kids at four, invoice Novák on Friday" into a list with times and reminders is a different job.

What already works in Czech on your iPhone

Before installing anything, use what's already on the phone.

Czech reminders through keyboard dictation

Apple's feature page lists Czech (Czechia) under Dictation. So the free way to add a Czech reminder is:

1. Open Reminders and tap New Reminder.
2. Tap the microphone on the keyboard. Make sure the keyboard language is Czech (tap the globe if not).
3. Say the reminder in Czech, for example "zavolat do banky kvůli hypotéce."
4. Tap the i to set the date and time yourself. Dictation writes text; it doesn't set the due time from what you said.

Two limits from the same Apple page. Czech isn't in the lists for Auto-Punctuation or On-Device Dictation, so you say "čárka" and "tečka" out loud and the phone needs a connection. And dictation is still typing, just with your voice: one reminder at a time, with the date set by hand.

Voice memos in Czech

Voice Memos records Czech fine, but it won't transcribe it. Apple's transcription guide covers the feature, and Czech isn't in the languages Apple lists for audio transcription in Notes or call transcription. If you record a Czech memo, you get audio you have to play back later. We wrote more about the built-in options in voice notes to text on iPhone.

Codot: a voice assistant you can talk to in Czech

Codot is a personal AI assistant you talk to. You say one messy sentence and it does the sorting: tasks with due times, calendar events, notes and details about people you know. It understands spoken Czech, as well as German, Swedish, English and Chinese. That's the gap we care about here, because the jobs Siri does badly in English for Czech speakers are exactly the ones Codot is built around.

You can reach it from the iPhone app, a Lock Screen widget, Apple Watch and the web, and there's an Android app on Google Play. The calendar syncs with Google Calendar, and each morning a briefing lists what's due.

What to say

These are the kinds of sentences Codot is meant for. You say them the way they come out:

• "Zítra v deset zavolat paní Dvořákové kvůli bytu na Vinohradech, a v pátek poslat Novákovi fakturu."
• "Přesuň schůzku s účetní na pondělí odpoledne."
• "Poznámka k Petrovi: syn začíná chodit do školy, zeptat se v září, jak to jde."

The first becomes two tasks with times. The second moves an existing event. The third is saved to Petr's contact, so it's there the next time you talk to him.

For a tap-free way in, put Codot on your iPhone Lock Screen, so recording starts without unlocking the phone.

What Codot can't do

Codot is an app for your plans, not a way to control the phone, so for calls, timers or HomeKit you'll still use Siri (in English) or the buttons. It doesn't browse websites, fill in forms or buy things for you. It can mishear an unusual name, in Czech or any language, so check what it created the first few times. On Android we haven't verified that the Lock Screen and watch shortcuts match the iPhone version, so we're not promising them there.

On price: Codot's free plan covers tasks, the calendar, notes, the personal CRM, habits, calorie logging and expenses. Reminders at a set time, repeating tasks, daily briefings, scheduled automations and email triage are part of Codot Max ($12.99 a month or $99.99 a year on the App Store, with 20x the free plan's usage). Every new account gets 7 days of Max free, then drops back to the free plan without charging you. Data is encrypted and never sold.

How we'd choose

Our opinion, as the team that makes one of these:

• You want to ask questions and chat in Czech: use the Gemini app. It's free and Google has documented Czech support.
• You only add a few reminders a week: keyboard dictation in Apple Reminders costs nothing. Set the dates by hand.
• Things come up while you're driving, walking or between meetings, and you want them saved with times without touching a list: that's what Codot does in Czech. If you've also been comparing English-language apps, see the best voice to-do list apps for iPhone.
• You want Siri itself in Czech: nobody outside Apple can give you that. Waiting is the only option.

FAQ

Will Siri get Czech with iOS 27?

Apple hasn't said. The iOS 27 feature availability page doesn't list Czech or Czechia for Siri as of October 29, 2026, and the June 2026 Siri AI announcement gave no Czech date.

Can I use Siri in Slovak instead?

No. Slovak isn't in Apple's Siri list either. Both Czech and Slovak are supported for keyboard dictation.

Is there a free to-do app I can use in Czech?

Apple Reminders with Czech keyboard dictation is free and already on your iPhone. You dictate the text and set dates by hand. Codot's free plan turns a spoken Czech sentence into tasks and calendar events; reminders at a set time need Codot Max, which every new account can try free for 7 days.

How is Codot different from Siri?

Siri controls the phone: timers, calls, settings, HomeKit, but not in Czech. Codot is an assistant for your plans. You speak Czech, and it creates and moves tasks, events, notes and contact details, syncs with Google Calendar and sends a morning briefing.

Does Codot work on Android?

Yes, Codot is on Google Play. Spoken Czech works there too. We haven't confirmed that every iPhone shortcut, like the Lock Screen widget or Apple Watch, has an Android equivalent.

If you've been waiting for Siri to learn Czech, try saying your next to-do to Codot on the App Store. On Android, it's on Google Play.
