Getting Started Omeka S module

Configuration

Global settings live under Oral Archivist > Settings and are available to global administrators only. Provider keys are never exposed to site admins: Supervisors and editors do not see the Settings menu entry or button, and opening the page shows them Omeka's Forbidden page (HTTP 403). Before 1.6.3, Supervisors could open and change these settings.

The page shows the current month's spend at the top and splits the settings into five tabs: Providers, Processing, Costs & budget, Prompts and Advanced. The tables below group the same settings by task.

The Oral Archivist settings page on the Providers tab, with the month's spend, the transcription and LLM providers, the API key field and the LLM model list
Oral Archivist settings

Providers

Setting Default Description
Transcription provider Mock mock produces a fake transcript at no cost; openai uses Whisper with word timestamps.
LLM provider Mock Used for the cleanup, segmentation and summary passes.
OpenAI API key Stored encrypted with the key from local.config.php. Leave blank to keep the current key.
LLM model Fetched from the provider with Refresh model list.
Default language auto-detect ISO 639-1 code such as en, passed to the transcription provider.

Review and queueing

Setting Default Description
Low-confidence threshold Words below this confidence (0 to 1) are flagged for review.
Auto-queue new audio/video media Off Process eligible media automatically on ingest, subject to the caps below.
Daily auto-queue cap Maximum media auto-queued per day.
Max attempts per job A failed stage is retried until this many attempts are used.

Costs

Setting Default Description
Monthly budget (USD) 0 (unlimited) Queueing is refused and running jobs stop once the month's spend would exceed this.
Transcription rate (USD per minute) 0.006 Used for estimates and actuals. Matches OpenAI whisper-1.
LLM input rate (USD per 1M tokens) 0.15
LLM output rate (USD per 1M tokens) 0.60

See Costs and Budgets for how these are applied.

Audio processing

Setting Default Description
Audio chunk length (seconds) 600 Long recordings are split into chunks of this length when they exceed the provider's upload limit.
Audio chunk overlap (seconds) 5 Overlap between chunks so words at the boundary are not lost.
LLM cleanup chunk size (characters) 12000 How much transcript is sent to the model per cleanup request.
ffmpeg path, ffprobe path auto-detect Detected in /opt/homebrew/bin, /usr/local/bin and /usr/bin. Set explicitly if the binaries live elsewhere.

Public display

Setting Default Description
Public transcript label "AI-assisted transcript, reviewed by staff" Shown near the public transcript.
Player style Basic One of five player bar styles. Sites can override it.
Page layout Classic How player, chapters and transcript are arranged. Sites can override it.
Placement on the page After Whether the automatic rendering appears before or after the page content. Sites can override it.

See Layouts and Styles.

AI summary

Setting Default Description
Summary metadata property none When set, the pipeline adds a summary pass and publishing writes the summary to this property on the parent item. Existing values in that property are replaced. Leave empty to disable summaries; the pass is then skipped at no cost.
Summary prompt built in System prompt for the summary pass.

Prompts

The Cleanup prompt and Segmentation prompt are the system prompts for the two LLM passes. The defaults are tuned for the JSON shapes the module expects; if you customise the cleanup prompt, it must still instruct the model to return the documented JSON shape.
