ConductSpeech
For research labs and universities

Run a whole study in one batch. Export to SPSS in one click.

ConductSpeech Research is a batch-first, API-first language sample analysis pipeline built for studies — not for one clinician on one laptop. Submit hundreds of samples at once, export to the stats package you already use, and never reformat another CSV by hand.

What the Research tier gives you

Every Clinician feature, plus the batch and export tools a study actually needs.

Batch the whole study, not one sample at a time

Submit hundreds of samples in a single API call. Get back a per-sample table plus aggregate means and standard deviations across your cohort — ready to merge into your analysis pipeline.

Exports your stats software already speaks

Drop straight into SPSS (.sps syntax + CSV), SAS (.sas syntax + CSV), or flat CSV for R, Stata, Python, anything. No proprietary binary, no licence-locked viewer.

A real REST API with your own key

Generate revocable API keys in your account settings — keys are SHA-256 hashed at rest and shown to you exactly once. Per-key usage tracking so you can split spend across grants or studies.

Reproducibility you can publish

Every metric we compute (MLU, TTR, NDW, PGU, DSS, IPSyn-lite, narrative scores) is documented in the API reference, with the formulas your reviewers will ask about.

Submit a study in one request

No SDK to install. Just curl, Python requests, R httr — whatever you already use.

curl -X POST https://api.conductspeech.com/batch/analyze \
  -H "X-API-Key: csp_..." \
  -H "Content-Type: application/json" \
  -d '{
    "items": [
      { "itemId": "P01-pre",  "label": "P01 baseline", "ageMonths": 48,
        "utterances": [...] },
      { "itemId": "P01-post", "label": "P01 12wk",     "ageMonths": 51,
        "utterances": [...] },
      { "itemId": "P02-pre",  "label": "P02 baseline", "ageMonths": 50,
        "utterances": [...] }
    ]
  }'

Response: per-item metrics, per-item advanced scores, and cohort summary stats. See the full API reference for the schema.

Your data, in your stats package

Hit /batch/export with the format you want and we'll generate the import scripts for you.

SPSS

Generates a .sps syntax file plus a flat CSV. Run the syntax in SPSS to import the CSV with the right variable types and labels — no manual data dictionary work.

SAS

Generates a .sas program with INFILE/INPUT statements aligned to a CSV companion file. Drop the pair into your project directory and submit.

CSV

Plain CSV with one row per sample and columns for every metric. Loads cleanly in R (read.csv), Python (pandas), Stata (import delimited), Excel — anything that opens a CSV.

Reproducibility, not a black box

We document every metric we compute and every formula we use. Reviewers and replicators get the same answers from the same input — that's the whole point.

MLU (morphemes & words)
Total morphemes ÷ utterances; Brown's Stages convention.
TTR / NDW
Lexical diversity, computed on cleaned word tokens.
PGU
Percent grammatically correct utterances.
DSS
Developmental Sentence Score, weighted morphological constructs.
IPSyn-lite
Index of Productive Syntax with the standard 56-item structure.
Narrative scoring
NSS, ESS, PSS rubrics with story-grammar element extraction.

Researcher questions, answered

What does a batch request look like?

POST a JSON payload to /batch/analyze with an array of items. Each item has an itemId, a label, the participant's age in months, and the utterances. We return per-item metrics, per-item advanced scores (DSS, IPSyn-lite, propositional density), and a summary block with the cohort means.

Where does my data live?

Audio is processed on our pipeline and not retained beyond the analysis run unless you explicitly save the session. Computed metrics live in your account so you can re-export them later. We don't sell, share, or use your data to train external models.

Can I use ConductSpeech for an IRB-approved study?

ConductSpeech can be used with de-identified language samples in research settings. We can provide a data flow description for your IRB application. We are not currently able to sign a BAA — talk to us if your protocol involves PHI.

How is the research tier different from Clinician?

Research adds three things on top of every Clinician feature: batch endpoints, the export-to-SPSS/SAS pipeline, and self-serve API keys. If you're running studies, those three things are the difference between a usable workflow and reformatting CSVs by hand.

Can I cite ConductSpeech in a paper?

Yes. Contact us at info@conductscience.com and we will provide a methods citation including the version of the analyzer used and links to the formulas.
