ConductSpeech
For research labs and universities

Run a whole study in one batch. Export a results table in one click.

ConductSpeech Research is a batch-first language sample analysis workflow built for studies. Submit many samples at once, merge study details, export a results table, and open the results in the stats tools you already use.

What the Research tier gives you

Every Clinician feature, plus the batch, study detail, 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 use in your analysis.

Exports your stats software already speaks

Drop straight into SPSS (.sps syntax + CSV), SAS (.sas syntax + CSV), a flat results table, or a starter Python notebook. No proprietary binary, no license-locked viewer.

API access 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

Choose the export format and we'll generate the results table, import scripts, or notebook 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 results table with one row per sample, study detail columns, and every exported metric. Loads cleanly in R, Python, Stata, Excel, or anything that opens a CSV.

Notebook

Generates a starter Python notebook that loads the results table, summarizes core metrics, and creates cohort summaries when a group column is present.

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?

Submit a batch request with each sample's label, participant age, optional study details, and utterances. ConductSpeech returns per-sample metrics and a batch summary.

Where does my data live?

Audio is processed for the analysis run and not retained unless you explicitly save the session. Computed metrics stay 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 batch analysis, study-detail-aware exports, SPSS/SAS import files, Python notebook export, and self-serve API keys. If you're running studies, those tools reduce the reformatting work between sample analysis and statistics.

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.
