Voice Typing in WhatsApp and Messaging Apps

WhatsApp has no voice typing of its own. When you dictate into the message box, the words come from your phone's keyboard, so the control you need is the microphone key on the keyboard. The microphone button beside the message box records a voice message to send. It does not type anything. People also use "voice typing" to mean two other things: turning a voice message they received into text, which WhatsApp can do with its own transcript feature, and sending a text by voice, which Siri or Google Assistant can do. This guide covers all three on iPhone and Android, and explains the most common reasons dictation stops working.

Dictating into WhatsApp uses your keyboard's microphone

Speaking is much faster than typing on a phone. In a controlled study on an iPhone, English entered by speech reached ¹, against ² on the built-in keyboard. The study counted the finished text, including time spent correcting errors. At those rates a 1,000-word draft takes about 6.5 minutes to speak and 19.2 minutes to type, a saving of about 12.7 minutes ³.

The gap matters most for longer messages. At 153 words per minute, a 60-character message of about 12 words takes about 4.7 seconds to speak on a phone ⁴. Ten hours of keyboard drafting would produce the same words in about 3.4 hours of speaking, before any editing time ⁵.

Those numbers come from short phrases in a quiet room, and the study's authors say that results outside the laboratory still need study ⁶. Treat the 153 figure as a measured result under good conditions, not as the speed you will get everywhere.

The two microphones in WhatsApp do different jobs, and most confusion comes from mixing them up:

Dictating on an iPhone

1. Turn Dictation on once. Open Settings, tap General, then Keyboard, and turn on Enable Dictation ⁷.
2. Open the chat in WhatsApp and tap the message box so the keyboard appears.
3. Tap the microphone key on the keyboard and speak. The keyboard stays open during dictation, so you can switch between typing and speaking ⁸.
4. Check the text before you send. Dictation stops by itself after 30 seconds without speech ⁹, so for a longer message start it again with the microphone key.

On iPhone, Apple says dictation is processed on the device in many languages and needs no internet connection ¹⁰. We counted 48 language and regional variants in Apple's feature table for On-Device and Modeless Dictation ¹¹. If your language is missing from that list, check the list before you rely on on-device dictation for it.

Dictating on Android

On Android, the keyboard is usually Gboard, Google's keyboard, which Google describes in its help pages. To type with your voice:

1. Tap the text field in WhatsApp.
2. Tap the microphone at the top of the keyboard. When you see "Speak now", say the message ¹².
3. If Android prompts you for microphone access, it offers three choices: While using app, Only this time, or Don't allow ¹³. Choose While using app if you dictate often. Choose Don't allow and voice recording is blocked.

Gboard has been able to recognize speech on the phone since 2019, when Google moved its voice typing to an 80 MB recognizer that works offline ¹⁴. That first release was for Pixel phones in American English, so do not assume every language works offline. Samsung Galaxy phones use their own keyboard, which has a separate guide: Talk to Text on Samsung Galaxy.

WhatsApp can turn voice messages you receive into text

WhatsApp's transcript feature turns a voice message you receive into written text, which helps when you cannot play audio. It is off by default ¹⁵. To switch it on, open Settings, then Chats, then Voice message transcripts, and choose the language ¹⁶. After that, tap and hold a voice message and choose Transcribe ¹⁷.

Only you see the result. The transcript is made for the person who receives the message, and the sender cannot see it ¹⁸. WhatsApp says its transcripts are generated on your device so that no one else, not even WhatsApp, can hear or read them ¹⁹.

When a transcript is wrong, check the language first. WhatsApp's warning lists a mismatch between the transcript language and the message language as one cause of errors ²⁰. Open Settings, then Chats, then Voice message transcripts, and pick the language the sender speaks ¹⁶. Then tap and hold the message again.

The feature does not dictate your own replies. It only transcribes voice messages other people send you, so for a reply you still use the keyboard's microphone from the previous section.

How many languages WhatsApp transcribes

At launch the language list was short, and it differed by platform. MediaNama reported that the Android version supported only a few languages, naming English, Portuguese, Spanish and Russian ²¹. It reported that the iOS 16 and later version supported 12 languages, including English, Spanish, French, German, Italian, Japanese, Korean, Turkish, Chinese and Arabic ²². That makes the iOS list three times as long as the Android one ²³.

These are November 2024 figures, and WhatsApp said it planned to add more languages ²⁴. Check the transcript menu for the current list. WhatsApp also warned that transcripts can contain errors when the transcript language does not match the message language, when background noise makes words unclear, or when the language is not supported ²⁰. If a transcript looks wrong, play the audio and compare before you act on it.

iPhone Messages and Google Messages transcribe audio messages too

WhatsApp was not first. In its launch coverage, Thurrott noted that voice message transcription was already a feature that Apple and Google offered in their own messaging apps ²⁵.

On iPhone, Messages shows a transcript under audio messages automatically from iOS 17 ²⁶. The iPhone Life how-to guide describes this as automatic. Both people in the conversation need to be on iOS 17 ²⁷. The guide does not list the supported languages in the text we read, so check your own phone if your language is unusual.

On Android, Google Messages has a voice message transcription setting. Android Central's walkthrough describes where to find it under the Messages settings ²⁸. Menu names differ between phones and software versions, so look for the transcription option rather than a fixed path. Android Central reports that Google says audio messages are not sent to the company and are processed on the device ²⁹. Google's own Messages help page could not be read for this guide, so confirm that statement in Google's current wording before you rely on it.

The table compares what each source says. Where a cell says "not stated", the sources we read did not cover it, so check the current help page for your phone.

Siri and Google Assistant can send a text without touching the phone

Voice sending is a separate skill from dictation. You speak a command, the phone asks for the recipient and the message, and it sends the text after you confirm. On iPhone, the iMore walkthrough describes this flow: say Send Message, choose a contact, dictate, then wait for Siri to read the text back. Siri confirms the content and sends it when you say yes or send ³¹. That walkthrough is dated, so the prompts may differ on current versions of iOS.

On Android, the 2021 Make Tech Easier guide describes a similar flow in Google Assistant. With the command "Send a message to" and a contact name, Assistant asks you to speak the message ³². Be cautious with these steps. In March 2025, Google announced that it would replace Google Assistant with Gemini on Android phones, and that Assistant would no longer be available on most mobile devices later that year ³³. Check on your phone whether Assistant or Gemini does this before you rely on a voice command for a message.

Voice typing failures in messaging apps are almost always keyboard settings

If dictation works in Notes or Messages but not in WhatsApp, the keyboard is fine and the problem is permission for that app. On iPhone, Apple's guidance is that if the microphone does not work in an app, you should go to Settings, tap Microphone and make sure the app is enabled ³⁴. On Android, the permission is the one you chose when Android asked for microphone access ¹³. That is why the same keyboard can work everywhere except one app.

When dictation fails in WhatsApp, the cause is usually a setting rather than the microphone. Work through these in order before you blame the app:

Two more issues are worth knowing. Dictating into a search field can send the text to the search engine to run the search ³⁵, so it is not the same as dictating a private message. And a WhatsApp transcript that is wrong is a transcript problem, not a dictation problem, so the fixes above do not apply to it.

If none of these help, the step-by-step guides for dictation not working on iPhone and voice typing not working on Android go through the rest of the checks, and the question on why voice typing fails in WhatsApp covers the messaging app specifically.

A dictated message is private only if the keyboard processes speech on the phone

Use this short check before you dictate anything sensitive into a messaging app:

1. Keyboard settings. On iPhone, open Settings, then General, then Keyboard, and look at what your device says about where dictated audio is processed ³⁶.
2. Third-party keyboards. If you use one, check whether Allow Full Access is on, and turn it off if you do not need it ³⁷.
3. Your language. On-device dictation depends on the language, so check it against the list before you assume your speech stays on the phone ¹¹.
4. Transcripts. WhatsApp says its transcripts are made on the device and that WhatsApp cannot read them ¹⁹, but only if you have turned them on ¹⁵.

Whether your words stay on the phone depends on the keyboard and on the language, not on the messaging app. On iPhone, dictation in many languages is processed on the device ¹⁰, and your iPhone shows in Keyboard settings whether dictated audio and transcripts are processed on the device or sent to Apple's servers ³⁶. Check that setting for your own language rather than assuming.

Third-party keyboards need a closer look. Apple's warning on third-party keyboards, as quoted by TechCrunch in 2014, says that if you enable Full Access, developers are permitted to access, collect and transmit the data you type ³⁷. Full Access therefore lets a third-party keyboard reach the text you type, so check that setting before you use it. The guide to offline voice typing on phones covers the offline options.

WhatsApp's own transcripts are generated on the device, and WhatsApp says it cannot read them ¹⁹. Android Central reports that Google says audio messages are not sent to the company ²⁹. Neither statement covers the keyboard's dictation, which is a separate path. For a deeper look at where voice goes, read the guide to speech to text privacy.

Which way to dictate or transcribe in a messaging app

The right tool depends on which of the three jobs you have. The table sets them out, and the chart above shows the speed gap that makes dictation worth the setup.

For transcribing audio files you already have, rather than messages, see the guide to transcribing audio to text. It covers recordings that a messaging app does not transcribe for you.
