Voice recorder vs audio recorder comes down to the features each maker builds in. Sony sells the ICD-UX570 and ICD-PX470 as digital voice recorders with voice operated recording, while Zoom and Tascam sell the H1n and DR-05XP as audio recorders with WAV up to 96 kHz, external microphone inputs and USB audio. A dictaphone is a dictation machine, a category that includes digital voice recorders (Wikipedia, Nov 12, 2026).

The DS-9500 costs $529.00 and has a slide switch, index marks and encryption, and it works with a docking station.
What is a voice recorder?
A digital voice recorder is a type of dictation machine, which is a sound recording device most commonly used to record speech for playback or to be typed into print (Wikipedia, Nov 12, 2026).
The pocket-sized digital voice recorder became possible in the 1990s, when falling memory prices let makers store sound on memory chips with no moving parts. Many early 21st-century digital cameras and smartphones carry the same ability built in (Wikipedia, Nov 12, 2026).
The Sony ICD-UX570, which Sony sells as a digital voice recorder, has a built-in stereo microphone, voice operated recording (VOR), Auto Voice Recording and Auto Music Recording modes that adjust levels, 4 GB of built-in memory, a microSD card slot and a 3.5 mm microphone input with plug-in power. It weighs about 48 g. The Sony ICD-PX470 has a slide-out USB plug, runs on two AAA batteries and records up to 59 hours and 35 minutes of stereo MP3 at 128 kbps on its 4 GB of memory. Its Digital Pitch Control changes playback speed from 0.25x to 3.00x.
What is an audio recorder?
Audio recorder is the name Zoom gives the H1n and Tascam gives the DR-05XP, handheld recorders for music, audio for film and video, podcasting, lectures and meetings.
The Zoom H1n has X/Y stereo microphones that record up to 24-bit audio at 44.1, 48 or 96 kHz in WAV and several MP3 formats. A 1/8-inch input takes an external microphone and supplies 2.5 volts of plug-in power, and the USB port lets the recorder work as a USB microphone. The H1n is discontinued. The Zoom H1essential is an X/Y stereo recorder that records 32-bit float WAV at 44.1, 48 and 96 kHz.
The Tascam DR-05XP is a 2-channel portable handheld audio recorder. It has omnidirectional condenser microphones rated to 125 dB SPL, records WAV at 16-bit, 24-bit or 32-bit float and MP3, takes microSDXC cards up to 512 GB, runs about 17.5 hours on alkaline batteries and works as a 2-in/2-out USB audio interface. Tascam names music, audio-for-video, meetings and dictation as uses.
Dictaphone meaning: what is a dictaphone?
Dictaphone meaning: Dictaphone is a trademark used for a dictating machine (Merriam-Webster, accessed Nov 12, 2026). A dictation machine is a sound recording device most commonly used to record speech for playback or to be typed into print (Wikipedia, Nov 12, 2026).
Dictaphone began as a company name. The name was trademarked in 1907, and the company was spun off as a separate business in 1923. It introduced the Dictabelt in 1947, which cut a mechanical groove into a plastic belt, so recordings were permanent. Magnetic tape followed, first on the standard compact cassette and then on mini-cassettes and microcassettes, which let makers shrink portable recorders. In 1985 Dictaphone and JVC released the picocassette, smaller than the microcassette. Nuance Communications bought the remainder of Dictaphone in 2006. The name became generic and now refers to any dictation machine (Wikipedia, Nov 12, 2026).
In digital dictation, a typist plays the audio file back with a foot switch (play, stop, rewind, backspace), or speech recognition software converts it to text (Wikipedia, Nov 12, 2026).
OM System's DS-9500 is a modern dictation recorder. It has a 4-position slide switch, insert and overwrite recording modes, up to 32 index marks per file and DSS, PCM WAV and MP3 recording. It adds 256-bit encryption with a 4-digit PIN lock, Wi-Fi to send the dictation to the office, 56 hours of battery and a dock that supports a footswitch.
Voice recorder vs audio recorder: what do the microphone and file format differences mean?
The microphone differences are pickup pattern and sensitivity, and the file format differences are PCM, MP3 and DSS.
Microphones. The Zoom H1n uses an X/Y stereo pair. The Tascam DR-05XP uses omnidirectional condenser microphones rated to 125 dB SPL. Sony's PX470 adds Focus, which narrows pickup to one speaker or source, and Wide-Stereo, which opens the field to a whole room or group. The OM System DS-9500 uses two microphones with beamforming and three sensitivity levels: high for conference recordings, mid for dictation and low for up-close recording.
File formats. PCM is uncompressed audio with broad playback compatibility, and MP3 suits storage and file sharing. DSS compresses efficiently and carries metadata for editing and workflow tools. The Sony ICD-PX470 records Linear PCM, which appears as WAV on your computer.
Controls. The Zoom H1n adds a headphone output with its own volume control and an external microphone input. The OM System DS-9500 adds a slide switch, insert and overwrite modes and a dock.
Software. Sony includes Sound Organizer software for Windows to manage and edit recordings, and OM System pairs its dictation recorders with ODMS dictation and transcription software.
Voice recorder vs dictaphone: is there a difference?
Voice recorder vs dictaphone is an overlap, because a dictaphone is a dictation machine and dictation machines include digital voice recorders (Wikipedia, Nov 12, 2026). Dictation adds a workflow in which the audio file goes to a typist or to speech recognition software, and law firms, healthcare organizations, accountancies and surveying firms are typical businesses that use dictation workflow software (Wikipedia, Nov 12, 2026).
The OM System DS-9500 combines editing controls (insert and overwrite modes and up to 32 index marks per file), security and transfer (256-bit encryption, a 4-digit PIN lock and Wi-Fi) and workflow accessories (a docking station with footswitch support and ODMS dictation and transcription software).
The DS-9500 is portable dictation designed for speech recognition, with a dictation mode for notes and reports. For a buying guide that sets traditional dictaphones against AI recorders, read Dictaphone vs AI voice recorder: how to choose.
Which one do you need: a voice recorder, an audio recorder or a dictaphone?
Pick by the job, then by what you want after you stop recording.
| Your job | Best fit | Reason |
|---|---|---|
| Long recordings of voices | Voice recorder | Auto Voice Recording, up to 59 hours 35 minutes of MP3 at 128 kbps on a Sony ICD-PX470, and VOR to skip silence |
| Music, audio for film and video, podcasting | Audio recorder | Stereo or omnidirectional condenser microphones, WAV up to 96 kHz at 24-bit or 32-bit float, an external microphone jack and a USB interface |
| Dictating notes and reports | Dictaphone | Slide switch, insert and overwrite, index marks, encryption and a dock with footswitch support |
| An audio file without buying a device | The phone you own | Many smartphones have digital dictation built in (Wikipedia, Nov 12, 2026) |
| A transcript, summary and action items after the meeting | AI voice recorder | An app transcribes and summarizes the recording |
| Phone calls you want transcribed | AI voice recorder that attaches to the phone | Comu Action Pro has a bone-conduction microphone and records a call when you attach it to the phone |
The Tascam DR-05XP takes microSDXC cards up to 512 GB, and the Sony ICD-UX570, the Zoom H1n and the Tascam DR-05XP have an external microphone input.
Run three questions in order. Do you need text afterward? Choose an AI voice recorder. Is the audio for other people to hear, such as a podcast or a video? Choose an audio recorder. Is the audio going to a typist or dictation software? Choose a dictation recorder. For anything else, a voice recorder fits. For the full buying criteria, see how to choose the best voice recorder in 2026. For devices that feed speech-to-text, see best dictation devices for speech to text.
Where does an AI voice recorder fit next to the three?
An AI voice recorder is a recorder paired with an app that transcribes and summarizes what it records, as with Comu Action Pro and Comu Note Pro. After you press stop, it gives you the audio file plus a transcript and summary, where the other three give you an audio file.
| After you press stop | What you hold | Next step |
|---|---|---|
| Voice recorder | A Linear PCM (WAV) or MP3 file | Replay it; the Sony ICD-PX470 sets playback speed from 0.25x to 3.00x |
| Audio recorder | A WAV file up to 32-bit float, or MP3 | Play it back; the Zoom H1n works as a USB microphone and the Tascam DR-05XP as a 2-in/2-out USB audio interface |
| Dictaphone | A DSS, PCM WAV or MP3 file | A typist or speech recognition software turns it into text |
| AI voice recorder | The audio file plus a transcript and summary in the Comu app | Read the transcript and summary, or ask Comu AI about the recording |

Let Comu AI transcribe and summarize after you press stop
Comu Action Pro and Comu Note Pro are voice recorders whose Comu app transcribes and summarizes what they record. Comu Action Pro costs €179.99 and Comu Note Pro costs €139.99 (Comu store, Nov 6, 2026). Both come with a free plan called Starter.
On Starter, transcription and basic summaries are unlimited, in 113 languages, with speaker recognition that labels who said what. Starter also includes Actions (to-do items) and Comu AI, which answers questions across your recordings. On Starter you tap to transcribe and summarize. Premium and Elite do it automatically. You subscribe inside the app, and the website does not sell subscriptions (knowledge base, Oct 27, 2026).
The hardware differs by model. Comu Action Pro has six microphones (four omnidirectional MEMS, one directional MEMS and one bone-conduction), picks up a room at 7 meters and stores 16 GB, about 1,000 hours at 16 kbps. To record a phone call with Comu Action Pro, attach it to the phone. Its bone-conduction microphone picks up the call. Comu Note Pro has two MEMS microphones and one bone-conduction voice pickup unit, picks up a room at 5 meters and also stores 16 GB.
Comu also works as software without a device. You can subscribe in the Comu app without buying hardware and upload an audio file to be transcribed and summarized. Choose a Comu Action Pro for rooms and calls, a Comu Note Pro for a 3.1 mm thin recorder that weighs 27.6 g, or the app alone for audio you already have.
