Your audio stays in this browser for playback. File support depends on the recording mode; supported protected DS2 files require the correct password.
Local playback and AI transcription are two different workflows. You choose whether to move from listening to submitting audio for transcription.
More than an audio preview
Playback controls for serious dictation work
Checking a dictated letter? Reviewing a case note? Skip the file-conversion detour. Open a supported DSS audio file, listen closely and mark the passages you need to revisit. The same controls work for medical dictation, legal notes and everyday business recordings.
Slow down DSS dictation
Set playback from 0.5× to 2×. Take your time over a name or number, then pick up the pace through familiar material. Five- and ten-second jumps keep short replays quick.
Repeat a difficult passage
Set a start point and an end point. A-B looping repeats just that section, so you can concentrate on the words instead of reaching for rewind.
Find a timestamp again
Click the waveform to seek or add a bookmark at the current time. Keep useful review points close at hand during the session, especially when checking a transcript against its source.
Adjust how speech sounds
Compare Original with Speech clarity, Medical dictation or Low-frequency cleanup. These are listening filters, not speech recognition or a way to restore missing audio.
File format guide
DSS, DS2 and recorder software: what plays here
DSS stands for Digital Speech Standard. It is a compressed audio format built for spoken dictation, rather than music. The .dss file extension identifies classic DSS recordings; .ds2 is associated with DSS Pro, which adds recording modes and protection options. Neither is simply an MP3 with a different name. Playback needs a decoder that understands the file's actual recording mode.

How to open it here
.dss · SP
Classic DSS dictation in SP mode.
Select the original recording. Once decoded, use the waveform and playback controls to review it.
.ds2 · SP, QP, QP7
DSS Pro recordings in the listed modes.
Select the file and check the detected format. Playback depends on the file variant and browser capabilities.
Protected .ds2
An encrypted dictation recording.
Enter the correct file password when prompted. Both the recording mode and protection method must be supported.
Other modes or unreadable files
Unlisted variants, incomplete transfers or damaged recordings.
A matching extension alone does not establish compatibility. Check the original file in the recorder manufacturer's software.
Scroll sideways to read all three columns.
Olympus and Philips dictation files
Looking for an Olympus DSS player or a Philips DSS player to hear one recording? Start with the file's mode, not the brand on the recorder. DSS appears in both manufacturers' dictation workflows, but encoding and protection determine whether a particular file plays here. SpeechText.AI is an independent service, not a manufacturer-provided player.
Playback is not file conversion
This DSS audio player opens supported recordings for listening. It does not export MP3 files or change the source audio. If you need to convert DSS files for another system, use a converter that explicitly supports the source mode and your required output format. Keep the original recording before making converted copies.

Clear boundaries, not blanket promises
Your audio stays local. The details matter.
The player reads your selected recording in the browser for playback. There is no audio-upload step, and opening a file does not alter the original on your device. You do not need to create a SpeechText.AI account just to listen.
For client, patient or employee recordings, local processing is one part of responsible handling. It does not, by itself, establish HIPAA, GDPR or other regulatory compliance. Follow your organization's policies, use a secure device and only open recordings you have permission to process.
Recording and playback
The selected audio is read by the local playback engine and held in browser memory for the player session.
Protected DS2 files
A supported encrypted recording needs its correct password. The password is supplied to the local engine, not a password-recovery service.
Website analytics
This page loads Google analytics and advertising measurement. Local audio playback does not mean that visiting the page makes no network requests.
Optional AI transcription
Transcription is a separate upload-based service with its own processing terms. A file selected here is not automatically submitted to it.
For work that needs a written draft
Need text, not just playback?
For dictated letters, reports and case notes, listening is only part of the job. SpeechText.AI's DSS transcription software creates text from supported recordings in a separate upload-based workflow. Check your audio here first, then move to transcription when you want a draft you can review.
Transcription is separate from free playback. Review current plans and processing terms before uploading confidential audio.
Check the source
Listen for missing sections, unclear speech and anything that needs a second pass.
Choose transcription
Open the dedicated service and submit a supported recording when you are ready.
Review the draft
Check names, numbers and specialist terms against the audio before using the text in a clinical, legal or business record.
Straight answers
DSS & DS2 player questions
File formats, Mac and Windows playback, protected recordings and the difference between a player and a transcription service.
What is a DSS audio file?
A DSS audio file is a compressed voice recording in the Digital Speech Standard format. It commonly comes from a professional dictation recorder and uses the .dss file extension. The related .ds2 extension is associated with DSS Pro. These recordings need a player with a decoder for their specific recording mode; changing the file extension does not change the audio format.
Is this online DSS player free?
Yes. Playback, speed control, waveform seeking, bookmarks and A-B loops are free for supported recordings. You do not need an account to use the player. SpeechText.AI's AI transcription service is separate from free playback and has its own plans and processing terms.
Can I use this DSS player on Mac or Windows?
Yes, for supported recordings in a current browser on macOS or Windows. Enable JavaScript and browser audio support; there is no separate installer. If you use Windows 10, check that your browser still supports your system. Recording mode and available memory also affect playback.
Can I open a password-protected DS2 file?
Supported protected DS2 recordings can be opened with the correct password. Enter it when the player requests it. The password is passed to the local playback engine; the tool does not recover, remove or bypass protection. If the protection method is unsupported, open the recording in compatible vendor software.
Can I convert DSS to MP3 or DS2 to MP3 here?
No. This page plays supported DSS and DS2 files; it does not export MP3 audio. To convert DSS to MP3 or DS2 to MP3, use software that explicitly supports your recording mode and provides MP3 export. Renaming a .dss or .ds2 file to .mp3 does not convert it.
Is this Olympus DSS Player Pro or DSS Player Standard?
No. This is an independent SpeechText.AI tool. Olympus DSS Player Pro, DSS Player Standard and DSS Player Standard R2 are separate desktop products. For supported files, this page provides browser playback and review. It does not replace recorder management, foot-pedal setup or the DSS Player Standard Transcription Module.
Does the free player transcribe DSS audio?
The free player is for listening and review, not speech-to-text. SpeechText.AI offers a separate AI DSS transcription service. Open the DSS transcription page to review the service and its plans before submitting a recording. Selecting a file in this player does not automatically upload it for transcription.
How do I repeat a phrase or mark a timestamp?
Set A at the start of the phrase and B at the end, then turn on A-B Loop. Use Bookmark to mark the current time. Treat loop points and bookmarks as session-only review notes, and copy important timestamps to your own records before closing the tab.
Confirm that the transfer from your recorder finished. Try the original in the manufacturer's software and check its recording mode against the compatibility guide. Do not change the extension to force playback.
2. Check protection and sound
For encrypted DS2, use the recording password, not an account password. If the file loads but you hear nothing, check the player's volume, tab mute setting and selected audio output.
3. Give the browser room
Decoded audio needs more memory than its compressed file size suggests. Close unused tabs, reload the page and select the file again in a current browser. Keep important timestamps in your own notes before reloading.
