Table of contents of this page
Conclusion.There are many articles that compare "fastest" by the number of seconds, but the number of seconds varies depending on the terminal, settings, and radio waves. In this articleIt will be the same no matter who counts- the number of operations that cannot be omitted, the number of screens to pass through, and whether it is necessary to open Obsidian - to compare the 5 route. If you say the answer first,If you have a free hand, "Automatic addition app" (automatic voice on at startup, iOS 26 or later compatible terminal, operation 2, Obsidian does not open), if your hand is blocked, "AirPods+Siri" (zero operation and screen zero screen depending on the setting during the lock)is the shortest in structure. If it's another job of transcription of recordings, the Whisper system is my real choice.

Decide the definition of "fastest" first - the route consists of 3 sections

"Inserting into Obsidian by voice" passes through the same 3 section on any route when disassembled.

  1. Until you can speak — Open the app, open the note, press the microphone, call Siri......The section with the largest route difference
  2. talk - All routes are almost the same here (the length of speech depends on the content)
  3. Until it is written in the notebook in the storage room — Whether it is written on the spot, processed later, or another app will add it on the back

In other words, it is the sections 1 and 3 that determine the speed of the route. And the difference between the section 1 and 3 can be compared as a structure by counting "operations that cannot be saved" and "passing screens" without measuring the number of seconds. The following table is the main body of this article.

5 route comparison table - read by the number of operations that cannot be omitted

"Operations that cannot be omitted" counts only the operations that must pass through that path (the operations that decrease if you are lucky, such as the state of the notebook that was opened last time, are not included in the number. On the other hand, the talking operation itself is common to all routes, so it is not counted).

routeOperations that cannot be omittedOpen Obsidian?PremiseThe scene to face
1 Obsidian Mobile + Keyboard Voice Input Start the app → Open the note → Microphone key (3 operation ~) Open (write with the main unit) None (can be used now) Postscript to sit down. When you want to talk while looking at your notebook
2 Shortcut + Obsidian Built-in Action (1.11+) Shortcut startup → Voice input (1 operation ~) You can add without opening Assembly of shortcuts. Obsidian Mobile 1.11 or later People who want to design a fixed type add-up by themselves
2' shortcut + obsidian:// URI (old method) Shortcut startup → Voice input (1 operation ~) Be sure to open to the front(structure of the URI scheme) Assembly of shortcuts Old environment where built-in actions cannot be used. Carbled characters and misdetonation of separate storage are chronic diseases of this method
3 Whisper plug-in Recording → Transcription execution → Note-taking (multiple operations + waiting for processing) Open Plug-in introduction (community plug-in activation) transcription of the meeting and long self-talk. " A tool to "wake up" rather than "insert"
4 Automatic add-up app (voice memo → vault) App launch → Send tap (2 operation. If "Automatic voice input on startup" is turned on in the settings, the compatible terminal of iOS 26 or later. If off, tap the microphone to add 3 operation) Does not open(The app is added directly to the storage folder, no plug-in required) App introduction + storage folder designation (first time only) Thoughts while walking and doing housework. How to save 1 lines in daily notebooks
5 AirPods+Siri (4 hands-free version) From 0 actions (say “Hey Siri、シンプルメモで残す”, then dictate the note. You may need to unlock the device, depending on its lock-screen settings and state.) does not open (The postscript is the same mechanism as 4. Sending emails and adding to the vault are different routes) 4 setting + Siri activation All scenes where both hands are blocked. Before driving, cooking, and walking

The detailed steps and stumbling points of 1 to 3 are "How to take notes with voice input to Obsidian 4 selection", and the usage and troubleshooting of 2/2' are summarized in "When the shortcut cannot be written to Obsidian". AirPods Hands-free Practice Guide is a dedicated page for 5 practices (AirPods stem setting, password wording, and actual machine screen).

Readable from the table - Only the "does not open" route can operate 2 or less

Reading down the table, the dividing line is whether Obsidian opens. Routes that open Obsidian (①, ②', and ③) always include loading the vault and reaching the note in interval 1. Routes that do not (②, ④, and ⑤) write in the background, through a shortcut action or a local file append by the app, so interval 1 is reduced to simply starting input.

For the “launch” step in route ④, this site’s published measurement is about 0.4 seconds: the time from tapping the app icon until the 1 character can be entered, measured as the median of 5 warm starts in 2026-8. The procedure and raw data are on the measurement-method page. This measures interval 1 of route ④. Interval 1 of routes ①–③ and ⑤ was not measured using the same procedure, so this article compares the number of operations rather than presenting side-by-side timings.

Conclusion of use

  • The top priority is not to erase the idea → 4 (If it is set to automatically turn on, operate 2 without going through the screen through 1). If the hand is blocked, 5 (0 operation depending on the setting during the lock). The assembly, including the remaining saucer, is covered in immediate capture workflow article
  • I want to add while looking at the notebook → 1. The microphone on the iOS keyboard is enough for audio
  • I want to automate it according to my type → 2. Use the built-in action after 1.11 (avoid the 2' URI method)
  • I want to turn the recording into text → 3. This is a different job from "plugging in", 3 is the best
About the actual measurement of actual use.This article compares only the structure (number of operations and number of screens). " The ratio of "which input method the user actually uses to leave a note" is not posted because there is no confirmed aggregate that can be published (the provisional value before confirmation is not posted either). The method of aggregation and the status of publication are"Voice Shift" fixed-point survey page.

Contents of 45 - Why can I "add it without opening it"

SimpleMemo, used in routes ④ and ⑤, relies on the fact that a Obsidian vault (Vault) is simply a folder. On iPhone, the app appends to that folder’s daily note through a local file write, so no plugin or launch of Obsidian is required. The same 1 line is also sent by email, except while “Save only to Obsidian” is enabled, so you can review it in your inbox even on days when you do not open Obsidian. Offline messages remain in the send queue and are sent automatically when connectivity returns. See the Obsidian integration overview for the complete mechanism and the dedicated daily-note append page for daily-note behavior.
