Thai Call Center Speech Dataset

Thai call center speech sourced to your specification — no inventory, no fixed listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.

Why call center speech in Thai is its own problem

A Thai customer service recording contains two registers at once: the agent reads a prepared script (formal, written form) and the caller speaks natural colloquial Thai (elided, with sounds swallowed). The two alternate inside the same phone call, so the transcription convention has to pick one standard first. On top of that, Thai is written without spaces between words, so the transcript needs an additional word segmentation pass.

The field to pin down first: The word boundary convention (as written / as spoken / delivered after word segmentation) belongs in the contract annex, and the three kinds of output must not be mixed in one batch.

What call center speech data is

Recorded customer-service calls, real or simulated, capturing both the agent and the caller side, used for call center QC, intent recognition, and dialogue systems.

What buyers get wrong about it

Compliance is what buyers fear most — call recordings involve personal data and recording consent, and the source has to be able to produce a consent provenance. This is also why we only do simulated collection and never work from intercepted real calls.

The specification field that decides the quote

Two-channel separated (agent and caller on separate tracks) or single-channel mixed — this directly determines how the data is annotated and how models are trained on it, and it has to be decided when the order is placed.

The language side: what Thai demands

Thai has five tones, and Thai script carries no word spacing — a sentence is one long run of continuous characters. There is no single right answer for where word boundaries go, which lets different annotators produce mutually incompatible corpora.

What we can put in this delivery

  • Read and conversational speech

    Scripted recording for TTS, and unscripted conversation for recognition. Specified separately because they need different speaker pools.

  • Transcription to your convention

    Orthographic or phonetic, with the guideline written before production and shared with you for review.

  • Speaker metadata

    Age band, gender, region and dialect background per file, so you can slice the dataset rather than take it whole.

  • Consent documentation

    Signed speaker consent covering the intended use, plus collection methodology and the annotation guideline.

  • Pilot batch

    A small batch first, which you can reject. Misalignments surface after a few hours rather than at delivery.

  • Delivery in your format

    Audio format, sampling rate, segmentation length and metadata schema set to your pipeline's requirements.

Questions we get about Thai Call Center Speech

How many distinct speakers can you provide for Thai Call Center Speech?

It depends on the specification and the timeline, and we will give a real number rather than a target. For this pairing, speaker recruitment is usually the step that sets the schedule. The word boundary convention (as written / as spoken / delivered after word segmentation) belongs in the contract annex, and the three kinds of output must not be mixed in one batch.

Can you annotate to our own guideline instead of the default?

Yes, and for this pairing we would recommend it. A Thai customer service recording contains two registers at once: the agent reads a prepared script (formal, written form) and the caller speaks natural colloquial Thai (elided, with sounds swallowed). That is exactly the kind of decision a default guideline leaves open, and it is where annotators diverge. Send us your guideline, or we will draft one and you can review it before production starts.

Do you offer a sample before we commit to a full run?

Yes. Select a free sample in the request form and describe what you need. A pilot batch is the cheapest way to establish whether the quality bar is reachable for Thai Call Center Speech before committing to the full volume.

Is the data licensed or owned outright?

Licensing terms are set per project, so tell us how the model will be used and whether it will be distributed. Consent documentation travels with the data either way, and we do not handle medical or clinical data or recorded telephone calls.

Other datasets in Thai

  • Thai Read Speech

    Recordings of speakers reading specified text, with clear pronunciation and known text, the base material for TTS and ASR.

  • Thai Podcast Speech

    Long-form podcast and interview audio, either solo monologue or two-person conversation, used for long-form speech recognition and speaker modeling.

    Speech data covering multiple languages within one project, used for multilingual ASR, cross-lingual transfer, and language identification.

  • Thai Noisy Speech

    Speech collected under background noise — street, in-car, restaurant, office and other real environments — used for noise-robust models and speech enhancement.

  • Thai Code-Switching Speech

    Speech that mixes two or more languages inside a single utterance — Hinglish, Spanglish, Taglish — used for recognition in real spoken settings.

  • Thai Children Speech

    Speech data from child speakers, grouped by age band, used for children's speech recognition and children's education products.
