Why names need a listening pass
Unpointed Hebrew does not show every vowel. A place or person name can be read in a way the writer did not intend. The local Hebrew engine uses a pronunciation model, but that does not remove the ambiguity.
Put the name in a short natural phrase and generate that line. If the reading is wrong, try a clearer spelling or wording and listen again. Do not rely on the written script alone as proof of the spoken result.
Numbers are a separate issue
For now, TTS Lines flags digits in a local Hebrew line. Write the number as Hebrew words so the intended reading is explicit. That also lets you choose the form that fits the sentence.
Keep the source number in your own draft if exact digits matter for a caption, price, address, or data point. Check the audio and the final displayed text separately.
Export only after checking
Generate one line, then the rest of the script. Listen to the full recording for changes in pronunciation between lines. After a correction, regenerate that line before exporting MP3, WAV, separate clips, or SRT captions.
