Retrieve a call transcript

GET
/v1/calls/{call_id}/transcript
curl --fail-with-body -X GET 'https://api.talki.it/v1/calls/38d23d84-02d2-4418-b169-3608aa04a8f8/transcript' \
-H "Authorization: Bearer $TALKI_API_KEY"

Return the automatic transcript of one call. calls:read does not grant it: the account owner ticks transcripts:read on its own. Requires transcripts:read. Limited to 600 requests per minute per account (API key) or per installation (OAuth).

call_id
required
Call Id
string
Talki-Version
string
Example
2026-10-01

Serve this one request at the given dated contract version instead of the credential’s pin. An unsupported value is refused with 400 unsupported_version, never downgraded.

Successful Response

Media typeapplication/json
CallTranscript

The automatic transcript of one call. The text is machine-made and can be wrong, so show it as an automatic transcript, never as a verbatim record. It is deleted with its call, and when the account stops keeping transcripts; from then on this endpoint answers transcript_not_available.

object
call_id
required
Call Id

The call this transcript belongs to.

string
utterances
required
Utterances

The turns, in the order they were spoken.

Array<object>
TranscriptUtterance

One turn of the conversation. Skip or mark a turn whose unreliable is true: its text is a placeholder. An omitted turn marks where the middle of a long call was left out.

object
speaker
required
Speaker

Who spoke. omitted is not speech: it marks where the middle of an unusually long call was left out, and its text says how many turns. The start and the end of the call are always kept.

string
Allowed values: caller assistant omitted
text
required
Text

What was said, as transcribed automatically during the call. It can be wrong: background speech may be captured as the caller’s, and a turn may come out in the wrong language. Not a verbatim record.

string
offset_ms
required
Any of:
integer
duration_ms
required
Any of:
integer
interrupted
required
Interrupted

True when the caller spoke over the assistant and it stopped: the caller heard only the beginning of text. Always false for the caller.

boolean
unreliable
required
Unreliable

True when the transcription of this turn was judged to be noise. text is then a placeholder, not something anyone said.

boolean
retranscribed
required
Retranscribed

True when this turn was transcribed again from the call audio after the call, and that transcription replaced the one made during the call.

boolean
source
required
Source

Which transcription pipeline produced the text. Today always gemini_live_sidechannel: transcribed live, during the call. Treat an unknown value as another automatic pipeline.

string
language_hint
required
Any of:
string
assembler
required
Assembler

Version of the code that cut the audio into turns. Rises when that changes, so two transcripts made differently can be told apart.

integer
created_at
required
Created At

When Talki stored this transcript, just after the call ended. RFC 3339 UTC.
