Persian Code-Switching Speech Dataset
Persian Code-Switching Speech delivered to your specification. A catalog entry, not a stock listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why Code-Switching Speech in Persian is its own problem
Persian code-switching is mostly Persian with English, but spoken Iranian Persian carries a huge stock of Arabic loanwords that are now fully nativized. Drawing the boundary around what counts as a switch takes an explicit rule. A fully nativized Arabic loanword should not be counted.
The field to pin down first: How far the Arabic loanword layer counts as Persian. It is fully nativized in speech, and treating it as switching would label ordinary Persian conversation as code-switching.

What Code-Switching Speech data is
Speech that mixes two or more languages inside a single utterance (Hinglish, Spanglish, Taglish), used for recognition in real spoken settings.
What buyers get wrong about it
The switch point is the hard part, where language A gives way to B inside a sentence, different annotators can place it several words apart. The guideline has to be fixed before annotation starts.
The specification field that decides the quote
Whether annotation marks word-level switch points or only tags the language of the whole utterance. The workload differs by a multiple.
The language side: what Persian demands
Written Persian and spoken Tehrani Persian are far apart: verb endings, pronouns, and connected speech all shift in the colloquial form. Transcribing spoken recordings against the written form produces text that does not match the audio.

Questions we get about Persian Code-Switching Speech Dataset
How many distinct speakers can you provide for Persian Code-Switching Speech Dataset?
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. How far the Arabic loanword layer counts as Persian. It is fully nativized in speech, and treating it as switching would label ordinary Persian conversation as code-switching.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Persian code-switching is mostly Persian with English, but spoken Iranian Persian carries a huge stock of Arabic loanwords that are now fully nativized. 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 Persian Code-Switching Speech Dataset 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.
