What are the publicly available websites for mapping (and collecting data) on vocabulary differences within a language?

For French there is

For English there is

Are there similar ones for German, Spanish, Italian, Russian, Mandarin, Hindi, etc? Are there better ones for French and English?

  • Do you think it would be better to ask this separately at each language specific site?

    There's also the George Mason University Speech Accent Archive, with hundreds of people pronouncing the same paragraph. Each person's production is available, along with an IPA transcription and data on age, birthplace, native language(s), etc. Strictly English pronunciation, but covers all native dialect areas and many foreign accents.
