Requirements and feasibility checked for this request
Audio annotation
Scope audio labels around speakers, events, and segments.
DD reviews audio condition, label targets, transcript needs, and sample acceptance before proposing audio annotation.
Discuss scope and secure transfer
Name the sound type and the languages spoken, and include one sample sound or a link.
Acceptance and ownership confirmed in writing
Dynamic Dialects reviews requests across 250+ languages. ISO types: ISO 9001:2015 and ISO/IEC 27001:2022. It works with 40,000+ vetted linguists. The written scope confirms staffing, coordination, and review controls for your request.
What DD checks before quoting
- Audio condition Noise, overlap, speaker count, file length, and language or accent mix.
- Label targets Speaker turns, intent tags, acoustic events, language tags, or segment boundaries.
- Transcript link Whether labels depend on a transcript and how timing aligns to speech.
- Acceptance sample A short audio set used to settle segment rules before larger labeling.
Example scope — actual checks vary by project type and client requirements.

What this request needs to settle
The buyer decides which acoustic units matter: speaker turns, intents, events, language tags, or timed segments. Audio labeling collapses when overlap and noise rules are missing. DD needs audio condition notes, label targets, transcript dependence, segment rules, and acceptance samples. A short hard-clip set settles boundaries before larger audio work.
Illustrative speaker-segment worksheet, not a client audio set
Illustrative request, not a client case or a promised result.
A support team wants caller and agent turns tagged with intent labels on noisy calls. Overlap and code-switching create disputed boundaries. This hypothetical call is not a DD accuracy claim.
- Inputs to check
- The buyer supplies rights-cleared sample audio, label targets, overlap rules, language or accent notes, transcript needs, and timing export format. Sensitive call content uses an approved transfer method. State whether timestamps use seconds, milliseconds, or sample indices, and how the receiving system handles gaps, overlap, and boundary rounding.
- Review decision
- Reviewers mark segment boundaries and intent candidates, logging overlap and uncertainty instead of forcing clean turns. The buyer settles disputed intents and updates the segment rule. Spot checks define disagreement handling.
- Acceptance method
- Sample output could contain file ID, segment start and end, speaker code, intent, language tag, uncertainty, rule version, and disposition. The buyer checks timing and labels on the sample before wider work. No word-error or intent accuracy claim follows.
- Exception to resolve
- If the buyer changes intent definitions mid-sample, affected segments are identified before rework. Audio the buyer cannot authorize stays outside the sample.
- Record to request
- Ask for a blank audio segment sheet with file ID, timing, speaker code, labels, uncertainty, rule version, and disposition. It contains no client audio.
Questions to settle before requesting a quote
- Which audio labels are required?Speaker, intent, event, and language tags need different examples and checks.
- How should overlap be treated?Define whether overlapping speech is split, dual-labeled, or marked uncertain.
- Is a transcript required?Say whether labels depend on words, timing alone, or both.
- Who accepts the timing export?Name the owner who loads segments into the evaluation or training tool.
DD checks audio rights, language, segment rules, and access feasibility for the request. No fixed accuracy, hours covered, staffing level, or model gain is claimed. The buyer owns label policy and final acceptance.
DD reviews the request, checks availability and requirements, and confirms the proposed scope and handling method in writing before work starts.
Sound labelling waits until DD has inspected name meanings, sample sounds, second-listener needs, and segment-file style.
Where this service fits
- Recordings that need speaker, intent, event, or language labels.
- Audio where overlap, noise, or code-switching affects segment boundaries.
What DD will confirm
- A proposed audio labeling and sample-review scope.
- Segment, transcript, and export terms to agree.
Questions teams ask first
Can annotation include transcription?
Yes when labels depend on spoken content. DD scopes transcription and annotation together only after the segment and label rules are clear.
Can noisy audio still be labeled?
Yes if the acceptance rule says how to handle noise, clipping, and unintelligible spans.
Do we need diarization first?
Only when speaker turns are in scope. State whether speaker codes are supplied or created during labeling.
Can call recordings be emailed for scoping?
Describe sensitivity first. Agree an approved transfer method before sharing restricted audio.
